How to Unlock FRP?

[ChojaK]

I dont have OEM options in dev menu, already rooted device and bootloader unlocked, I even installed TWRP and LineageOS - now i wanna update device but cant update TWRP because FRP is unlocked

Well, you need the OEM unlock option in the first place to lock the FRP.
As of how to do it?! I'll look in the forums and see if I come by anything
