Will BIOS support PCIe network card (with PCIe extender) connected to PCIe port? How many lines is it?

It's a laptop mainboard, there is no PCIe slot. Or do you mean nvme -> PCIe adaptor?

Another option is to put the nic inside a tb3 pcie enclosure and connect that. There are 4 thunderbolt ports.

From what I could find tb3 to PCIe is very expensive. NVME is basically a protocol on top of PCIe with m.2 connector.

Here's an example of m.2 to PCIe x4 adapter: https://www.delock.com/produkt/64131/merkmale.html

If adapter is possible we could use 4 port gig adapter for a nice pfsense/opnsense router or a VM server.

Understood, I actually have a m.2 to PCIe adaptor on hand now that I use with success with my honeycomb lx2. I'll test a nic for you with the framework m.2 port.
