Apologizing to my father for his abuse to see my sister?!!!

Hey everyone, I really need some advice. I’m 18 years old and it’s been 3 years since I have seen my younger brother and sister who I was very close with. Going on a vacation with my dad, step mom, and 2 siblings, my dad and I got into a stupid argument because I was listening to music with one airpod in and he didn’t like that. Anyways, he ended up pulling over and hitting me so I had to go to the hospital and my mom met me there. I don’t want a relationship with him, but I want to see my siblings. He believes I was in the wrong that day and tries to gaslight me into believing it’s my fault. I wanna see my sister whose now 15 and needs a good role model. He told me the only way I could see her is if I apologize to him for causing what happened “that day”. Should I fake apologize to him to see my sister or go about it differently? I don’t really want to give him the satisfaction of me justifying his actions but I might to see her. Lmk what you think.
