TouchDispaly configuration

I am running Volumio (current system version 2.671) on RasPi 3B+/HiFiBerry Miniamp/ 7“ touch display. Calibration of the touch display requires adding the following 3 lines into /boot/config.txt:

hdmi_cvt 1024 600 60 3 0 0 0

Trouble is that these entries disappar after each version update, the display needs to be recalibrated accordingly.
Question: Is there a way to prevent this issue?
Thx for any helpful idea.
