@Manuekris, every intervention in the running system has its risks. But so far I have not been able to detect any “dangerous” system reactions in my experiments.
Before you make any changes, I recommend that you make a system backup to an external microSD card. That way you can your /e/ OS “stable build” save and in case of an emergency like going back to the beginning /e/ OS ROM.
With the already installed TWRP Recovery we can make a device-dependent backup (Nandroid-Backup) and pull this data over to the PC or store it on an external mircroSD card. See also → A complete system backup without root with TWRP Custom Recovery including EFS / IMEI on external microSD card
