Original Note:
Rockets do not require anything to "push off of" in a vacuum. The exiting exhaust mass creates a forward reaction (Newton's Third Law) on the rocket body. The thrust equation actually works more efficiently with no ambient pressure (Po). https://www.astronomicalreturns.com/p/section-33-rocket-thrust-equation.html
