Directly set level/percentage/height of LED bar

I’m using both LZW36 and LZW31-SN. As far as I can tell, the configuration options for the LED light bar only allow me to set the brightness, and optional blink/pulse/chase. But what I really want to set is a percentage, like the switch natively does itself when you dim up and down, but I want to be able to do this without dimming the attached load. It almost works on the LZW31-SN if I set the switch into smart bulb mode (param 52), but it still shuts off the load if brightness goes to 0, and param 52 doesn’t exist on LZW36.
Any other way I can do this? Maybe we could get more effects or more direct LED bar control in an update?
