update to advanced background check??

Hi all-- back to Rover after some time away. I am updating my profile, and I think I'd like to update my basic background check for the advanced. I'm not seeing any answers to my question anywhere, which is : if I already have the basic, can I upgrade to the advanced ? All of the help articles say to go to "background check" on my profile but I don't even have that option! If I'm able to upgrade this, how/where do I do this? Thank you so much!!! Missy
