Discontinuation of Official Bootloader Unlock Service
Although realme has discontinued bootloader unlock support for the RM6785 series, you can still unlock it using the mtkclient tool.
However, this method will corrupt the dm-verity and require you to press the power button on each boot.
To fix that, you can use Roger's lk patcher to patch your lk (bootloader) partition. It will get rid of the corrupted dm-verity.
Alternatively, if you have a backup of the seccfg partition (created when the device was unlocked through official method), you can flash it using mtkclient to avoid dm-verity corruption.
