No, use the dealer gasket by itself. No sealer either.
As previously mentioned - with ANY gasket the pan has to have a flat flange.
Spend time on a flat surface plate and get the pan rail flat using a punch a little larger than the pan bolt hole size.
Lay the pan flange down, tap the hole flat. Check every hole.

Then flip it over and use a long straight edge to make sure the flange and those bolt holes are all flat.

Make sure every bolt hole in the case is clean with no debris in them.
Hand screw a bolt in each hole and make sure they go all the way in to the washer - I’ve seen guys chasing leaks to find out the bolt was too long, or the case had garbage in the hole.
