Hey guys, after I was searching for such a solution, for a longer time, here the answer:
We can modify /system without issues under Android 10:
Just use latest TWRP (recovery-TWRP-3.4.2B-1206.img by LR team)
than I used:
xiaomi.eu_multi_HMK30Pro_20.8.7_v12-11.zip
root with latest magisk 21.1
than use Disable_Dm-Verity_ForceEncrypt_11.02.2020
and you are good to go.
no hang on reboot after modifying /system
