I find that I spend too much time ensuring that I get every speck of support material off the print plate long after I’ve removed the actual print.
When it comes to the skirt, I always set it to be two layers tall for this exact reason, and I was hoping it’s possible to do the same with the support base.
EDIT: PETG on textured printsheet



This looks like a small print, suitable for experimenting. Try tilting it 45 degrees so that it is tilted against the bed. It won’t have much contact to the bed but may need way less support and the layers may even strengthen the print.
I’d tilt it so that the flat backside faces towards the bed but do try various versions, see how it goes and also evaluate strength
Edit: oh… Hadn’t seen the frame around it 🤦
