Natural carbonation in Oxebar 20L with Kegland 360 Mini Regulator

I’m fermenting directly in an Oxebar 20L keg and planning to naturally carbonate in it. I have the Kegland 360 Mini CO₂ regulator connected, but I’m a bit unsure how to manage carbonation during fermentation.

Since the regulator only holds a fixed pressure (e.g., 0.8 bar), it doesn’t make much sense to keep it connected – the internal pressure will keep rising as fermentation progresses, and the regulator won’t vent any excess pressure.

Should I just remove the regulator during fermentation and let the keg build up pressure naturally? Or is there a better way to handle this setup?

Appreciate any tips
