how to change primary console without having the original?

(if flair isn’t right please feel free to change it mods)

i recently bought a subscription in a game where it requires the switch I’m currently using to be my “primary console” on my switch2 but my old switch that is the primary broke a few years ago and i can no longer use it. i tried a couple youtube videos but the Nintendo website has changed since then and I’m wondering if theres another way i can do it i haven’t found yet or if i just need to call Nintendo support?
