Install Magisk in TWRP, with "Keep DM-Verity/AVB 2.0" option?

I want to flash the Magisk ZIP while keeping dm-verity and AVB 2.0. The Magisk ZIP detects my encrypted /data partition and keeps force encryption, but always disables dm-verity and AVB 2.0 when flashed with TWRP. This leads to the inconvenience that I have to restore the "stock boot image" (with TWRP) and flash it again in Magisk Manager. It's better if dm-verity and AVB is preserved at the first flash in TWRP.
