Is it possible to shorten the space between icons in the dock widget?

I would like to have less space between the icons so I can fit more icons and have them all be visible without scrolling. Didn't see any options to change it and played with the "free space after button" and "extra padding" but i didn't see anything change when playing with those.

also, if i do have it so it is scrollable, is there anyway to have it so you can 2 finger scroll the touchbar dock on the touchpad? I already have it set so i can control touch bar with my mouse
