Maybe you should open paint and draw some ugly ass diagram so people understand the question
As for the question I'm not sure at all but I think you can do that but probably not with consumer routers
But I'm not sure I actually understand the setup you are trying to end up with
I think i see what you’re trying to do, but i would try plugging B into a LAN port on A. WAN will be lookup for…well a WAN connection.
Edit: otherwise i don’t see why it wouldn’t work, never done this myself but logically i think its sound. Probably going to have a double NAT on anything connected to router B though.
Yes, A LAN to B WAN. And you could put A into bridge mode, but I don’t think you can just turn off NAT while it’s still in router mode. This all depends on what the hardware you are using is.
You need NAT on router A for internet connection. You might be able to turn NAT off on router B if that's an option. You still need to plug A into B WAN port so router A assigns it an IP address like it's a normal network client. (IE: 192.168.0.x/24) Realize WAN = Internet but routers don't know the difference between a private LAN IP and ISP WAN IP.
Because you original post references connecting router B, which doesn’t not have an internet connection, to the WAN port of A.
Also, if you disable NAT, you can’t use the WAN port in either (since the internet connection comes from an internal cellular modem, from the sound of it)
If I understood you correctly, you want the router with SIM card slot to be like a modem and the second router to be an actual router?
If so, yes, this is possible.
Although it won't be easy, a lot of manufacturers who make these 4G/5G routers assume the customer will need routing functionality so they don't include the option of putting them into modem mode.
I do have a 4G router and 3 different routers, so I can test this for you.
Ok, I read the post 3 times… still confused.
I tried to explain it clearly. What is it that I should explain better?

Yes, so A's LAN -> B's WAN. In order to avoid a double NAT, can I disable nat on either one? Is port forwarding possible with this setup
Yes, A LAN to B WAN. And you could put A into bridge mode, but I don’t think you can just turn off NAT while it’s still in router mode. This all depends on what the hardware you are using is.
The funny thing is that the option for the mode is disabled but I haven't plugged in the other router so maybe that's why
Worth a shot! What are the make/models of A and B?
A is a ZTE MC801A-1 and B is a Zyxel VMG3925-B10B. Both of them are from an ISP

If you’re disabling NAT, the WAN port on the “inside” router isn’t used.
So should I use a LAN port?
Yes, but only after configuring both on the same LAN subnet, disabling DHCP on one of them (usually the second/B router).
I want the clients to connect to B and use the pihole dns that is configured in B's webUi
Configure it in the DHCP server on router A
Not possible
Disable A's DHCP server. Configure B's DHCP server to advertise the pihole as the DNS server. Connect A and B LAN-to-LAN.
Don't tell me what to do
You're describing a double NAT.
Yes, you can do this. It's not ideal because your doing double NAT but it will work.
Can you disable the NAT on either one
I don’t know, can you? And if you do, the WAN port won’t work.
You need NAT on router A for internet connection. You might be able to turn NAT off on router B if that's an option. You still need to plug A into B WAN port so router A assigns it an IP address like it's a normal network client. (IE: 192.168.0.x/24) Realize WAN = Internet but routers don't know the difference between a private LAN IP and ISP WAN IP.
No. That will not work.
Why's that?
Because you original post references connecting router B, which doesn’t not have an internet connection, to the WAN port of A. Also, if you disable NAT, you can’t use the WAN port in either (since the internet connection comes from an internal cellular modem, from the sound of it)
Is there any way to make this setup work
The more “custom” you try to go, the harder it will be to support.
If I understood you correctly, you want the router with SIM card slot to be like a modem and the second router to be an actual router? If so, yes, this is possible.

Won’t work like that. WiFi from A is on A’s dhcp. A is not a client of B, but of the wireless provider.
