If a card is affected by "can't activate [When Digivolving] effects," can I process just the "by" condition in its [When Digivolving] effect?

This card with ST22-01 [Viximon] in digivolution cards attacks, and I use this card's [When Attacking] effect to use an Option card. If I use ST22-01 [Viximon]'s inherited effect to digivolve this card at such times, does this card's [End of Attack] inherited effect trigger at the end of the attack?
