How to disable avb on devices that use EROFS on super?

I understand and can patch avb on devices that don't use EROFS filesystem as we normally just edit `/etc/fstab` which is normally in boot.img or boot.bin or in boot_a.bin with devices that A/B or plain images. The main issue I have is that when you have just modified your system or super your changes don't appear untill you have disabled avb, especially on devices that no longer use ext4 images.
