Unlock Bootloader (Read-only)

Thin q
I was wondering if there is any way to flash the google fi firmware for the lg v35 to the att version of the lg v35. I want to switch carriers from att to google fi and would like a fully functional version of the google fi variant., As the phones are identical in everyway except firmware. Please list any possibilities to do this as I don't really want to buy a google fi variant just to have the added functions. The phones are identical they shouldn't be locked down like that when both firmwares are legitimate lg and for the same exact hardware
