Yes, this was with a T-Mobile phone. You unlock the bootloader, take boot.img from the lolinet link, patch it in Magisk, and flash through fastboot.
Motorola phones are perfect for you then, I use them exclusively when tethering to a routers. Always easy to root. No dun restrictions in apn settings. All carrier spyware is in the product partition, easy to suss out and disable. Can't beat it.
