Which LTE/5g modems/routers supports flawless bridge mode/passthrough

I live in a location with no decent cabled internet, so I am looking at a 4g/5g solution as this should give me a decent speed over my cabled alternatives

But I need an unfiltered, 100% bridge/passthrough solution where this ISP public IP passes through un-NAT'ed to my internal firewall.

I found the Zyxel LTE5388-M804

Will this also allow setting up your own APN (in order to get static IP address)

Or are there any better Zyxel 4g/5g solutions, that can do this? Or other products than Netgear?
