Buy supplement Nozomi Shinkansen Ticket

I will be travelling to japan next week and i’ve bought an Hokuriku Arch Pass as i want to visit Tokyo, Kanazawa, Kyoto and Osaka.

But i got a last minute ticket to the nintendo museum and i need to get to Kyoto as fast as possible from Tokyo. It is possible to buy a Nozomi Supplement ticket as a Regional Pass holder or i will have to pay full price for it?
