Installing the Policy JSON Configuration for Brave Flatpak on Bazzite

Hello, I have a problem regarding Brave Flatpak on Bazzite.

Today I discovered the existence of the Policy feature

brave://policy

brave://policy

that allows to get rid of bloated features in Brave, and I have the json configuration that get rids of the bloats on Linux Flatpak version of Brave.

However, the main problem is that currently Brave only reads directory

/etc/brave/policies/managed

/etc/brave/policies/managed

which means I cannot install this with Bazzite since this is an immutable distro (There is already a way to overwrite the /etc/ folder temporarily but you know that way is discouraged)

Is there any way to make Flatpak Brave read the custom policy file
