It has the same meaning as vbmeta.avb.json. But obviously, changing flag bits in "boot.avb.json" is not well supported :) Do you have real world requirement to change the flags? For debugging?

I even don't know boot.avb.json flag mean what.also has the same meaning as vbmeta.avb.json? when I use magisk 24.3 Patch boot can normal boot ,but use magisk 25.2 device into 900E, So I think flag will help me...

怀疑flag的话，可以直接把vbmeta.img的flag设置成2,就禁用所有verification, 后面所有image的flag不需要设。

How to disable AVB verification
The idea is to set flag=2 in main vbmeta.

rm *.img
cp <your_vbmeta_image> vbmeta.img
./gradlew unpack
vim -u NONE -N build/unzip_boot/vbmeta.avb.json  -c ":19s/0/2/g" -c ":wq"
./gradlew pack
Then flash vbmeta.img.signed to your device.

哈哈哈哈～magisk未必能把所有boot image 改好。可以自己去改，改完刷上去试。

Close it for now. You can reopen it if you still have any questions.
