Hi,
Was there a thread on this very topic recently? If I remember correctly, those knobs must be pried off the shaft.
There is no "grub screw". Equal force from under both sides of edge of the knob is essential, and damage to the knob is likely.
May I suggest you reconsider the need to get the pot out?
