With keyboard Wall Kicking while gliding is only possible if it's set to auto currently. I press space when prompted and instead of jumping up wall it cancles glide. Spamming it just keeps reactivating and cancelling glide.
There's also no settings to make Glide only activate when holding space, which is something I spent several minutes looking for when I started playing and was surprised there was no option for it.
And remapping any of these functions isn't allowed either. Please expand the options available for glide and wall kick.
