There’s no way to set it as default completely. You can set it as default for titles that Valve hasn’t explicitly overriden, but if Valve decides that a certain game works with Proton 8 or Hotfix, it will automatically install those. I really wish there was a way to force Experimental in all cases.
You can enable such an option in the settings
