Cannot edit mixer_paths_tasha.xml on android 10

Question

I wanted to edit mixer_paths_tasha.xml to change RX0 value from 84 to 95.
I am currently using havoc 3.0 on oneplus 3.
Havoc os has low call volume bug which can be rectified by above changes.
But ever since I updated to android 10 I am not able to edit the above xml file.
It's location is /system/vendor/etc.
Editing using any root explorer results in error that given file cannot be moved from tmp folder to etc folder.
Please provide a way to edit the file.
It's a read only file system.
Please suggest a way to mount is at write file system
