Can I change my police report statement that my boss told me to say or im fired

I got into an accident with a customer\'s car that was insured but had not been signed for being that I needed to get some customization\'s done. I fled the scene because I have high anxiety plus my boss told me he would fire me unless I told the police the car stolen instead of it being in an accident since I was not driving on dealer plates which is not legal but all employees are told to do if if there are no dealer plates. No matter what I am leaving this company because they have shady business within the company that are federal charges I believe. They got raided once. This all happened fast and I didn't think logically can I change my story with the poilice to the truth and then just find a more reputable company
