If [DarkKnightmon] or [X Antibody] is in this Digimon's digivolution cards but I can't delete a Tamer because neither I nor my opponent have any, does this card's [When Digivolving] effect unsuspend this Digimon?

If [DarkKnightmon] or [X Antibody] is in this Digimon's digivolution cards but only I have a Tamer, can I choose to not delete my Tamer with this card's [When Digivolving] effect?
