2020 X5 sdrive40i towing?

Hi there. I bought a used X5 and I’m curious if I can expect to tow a small trailer. I don’t believe I have the tow package so my first question is how much can I tow with an after market tow package? Second question is: the trailer we’re looking at is an Apex Nano with dry weight of 4200 and tongue weight of 512 (I think), is this towable? We would be pulling it to RV places so we wouldn’t be hauling heavy items regularly.
