Rivian Tailgate Pad can’t be shipped to California?

I’m in NorCal and taking delivery of an R1T in a few weeks (stoked)! My family mtn bikes and I wanted to get the Rivian Tailgate Pad for my new truck but got a message from the gear shop that it can’t be shipped to California. I also reached out to my Rivian guide and he confirmed.

Any Rivian owners experience this and find a way around it? Any recommendations for an alternative? I was hoping for one with the light bar cutout but not sure any others manufacture for a Rivian specifically.
