Using Petasan 2.2.0 is it possible to create a cluster using only 2 nodes and modify the default vote value to validate the quorum if one node falls?

You need at least 3 nodes since with 2 it can lead to split brain, forcing a value is not a safe solution.
Probably something you may want to do is have your 1st machine as a vm with low resources, and do not assign any storage or iSCSI service roles to it ( uncheck the checkboxes during deployment ). Your 2 other nodes could be real machines with lots cores/disks..etc. The vm node should be run from another system not stored on PetaSAN.
