Interesting, why can't you do that with SIP? (not a Mac user)

From what I understand, Apple removed the ability for TB2. In order to use an eGPU, some system files need to be patched [0].

0. https://github.com/mayankk2308/purge-wrangler

Can't they be patched once, and then re-patched when system updates change make changes to system files?

Could, it's just a hassle.

I'm in a similar boat with a kext that enables unsupported Thunderbolt 3 docks.

Yep. I make some changes that SIP would catch, but I'm mostly comfortable with the boot into Recovery -> run a script -> boot back again. It's not kext stuff, though.

I might have to use PurgeWrangler for an older iMac. Apparently, can keep it mostly enabled, but you need to mind updates and be ready to recover if your modifications are invalidated https://github.com/mayankk2308/purge-wrangler/issues/2#issue...

Presumably the driver is not signed with a kext developer certificate, which means SIP must be disabled for macOS to load it.
