No. Only Pro 2023 and newer have the option to disable certain devices (they will dissappear from Ghome!)
No clue if that’s controllable by flows though.
Or do you mean to control the devices (on/off) from Homey Cloud?
That is possible when you ‘misuse’ a KaKu (Trust Smart Home) wall plug;
Have fun (to be clear: you don’t need any physical KaKu devices):
