The first question would be, "What do you want to change and why?"
The next is: Are you using a Magisk module to do this?
Since time immemorial /system has been mounted read-only in Android. So if we were talking about a 10 year old Android Jellybean phone I'd point to that.
Since we're presumably talking about a modern Onyx device, I'll point out that /system is not only mounted read-only, it is protected by dm-verity and FEC error correction. If you are using Magisk and if you have written a custom Magisk module to "shadow" the read-only /system/build.prop with your custom version in /data/adb/modules/Whatever/system/build.prop, then ok.
Finally, there is the Magisk-free method which involves actually changing /system, which gets a bit more complicated. I do that.
