A207M Magisk patch does not work on boot.img, SECURE CHECK FAIL Boot.img

[Gokugokuuuuu]

I tried to root with magisk and it still doesn't work even though the OEM is unlocked. The KG status is "checking" and the OEM Lock is off (U) but it still doesn't work on any magisk version.

Device:A207M
Android version:11
Magisk version name:28.1
Magisk version code:28101
