Nonetheless, if you make the control big enough to show the slider circle, you can actually use the slider directly on the UI by moving the slider circle, without opening the percentage bar.

Turned on / off examples:
Things to consider for better experience: disable the "Update Values While Moving" on the Operation menu.Best regards
