root - Can't edit hosts file

I am using Redmi Note 11 running on Custom ROM - Xiaomi Eu Specs: My device is rooted via Magisk. I want to edit the hosts file. I have tried using ADB, CX File Explorer, X-Plore Manager but I am unable to edit it. Apparently none of the methods are able to write on /system partition because it is Read Only System. I looked up online and tried mounting it as writable via ADB using adb shell su mount -o rw,remount /system Output : /system not in /proc/mounts And mount -o rw,remount / Output : /dev/block/dm-0 is read only adb root and disable-verity aren't working either. It is so annoying. I had to wait 5 days to unlock the bootloader. Spent whole night installing Custom ROM and rooting my device. And all of it for nothing. Please help.
