Not sure if it was here or somewhere else, but unless I'm mistaken or we're not talking about the same gasket, most cars already don't have this gasket (after march 2019 from memory).There’s a well-known service bulletin for this, Tesla remedied this via mobile tech in 10 minutes on both of my B pillars under warranty; it involves removing a foamy gasket in that camera housing to allow better air circulation thus minimizing potential for condensation.
Tesla will take care of it.
