Disable decals for android low profile?

Hi,

I’d like to know how I can disable the decals only for low-end Android devices. I know that by unchecking the mobileHDR flag in the project settings, the decals disappear, but this disables the decals for all the devices. I tried putting the +CVars=r.MobileHDR=0 for the [Android_Low DeviceProfile] in the DefaultDeviceProfiles.ini, but when I put that line there, the game just crashes on startup.

I’d appreciate if someone can help me.

bump! Can anyone help me?
