Font too small, of mangohud/performance overlay on 4k TV

Hi, I am using bazzite-deck on my HTPC. The performance overlay is too small for my 4k TV.
I tried adding

MANGOHUD_CONFIG=font_scale=3.0

MANGOHUD_CONFIG=font_scale=3.0

to /etc/environment and it did kinda work but it then stayed on forever and the "Performance Overlay Level" option stopped working. I assume it's cause the env var overrides instead of appending options to mangohud config...

Is there any way to scale/change font size of the overlay while still keeping the steams "perf. overlay level" option still working?

Solution

Solved: I installed a decky loader plugin called MangoPeel, it allowed me to customize.
