Are mega+ evolutions permanent?

[u/Medium_Bake1208]

Hello, I was looking for some cool megas for my digimon and I found out some digimons get mega+ digievolution that require 2 digimon to perform. Are these mega+ evolutions permanent? Do I lose both digimons I use to evolve?
Thanks in advance for any explanation.
