It’s me again there no really way to bypass xiaomi unlocking process of bootloader on phones based on snapdragon .Just install virt-manager with qemu install windows 10 there and make USB passthrought to virtual machine.Also u will need to create mi account then go developer options in miui link ur account in mi unlock and use phone after linking during one week like that otherwise xiaomi server gonna count phone as stolen or else I don’t know if u gonna try unlock phone mi unlock in windows it gonna give u banner to wait for one week and then do next attempt again.Ah and yeah u need insert Sim card and make linking account using mobile internet. And u can find more roms there are actually a lot again here https://4pda.to/forum/index.php?showtopic=1053816 .Also I offered voltageos cause it have features similar to graphenos about sandboxing Google play services

i mean you can do it in a windows vm or something
