Collective - Month 3- ATP - Regeneration Sequencers

Regeneration Sequencers states
Is the "Or..." only triggered when an upgrade is discarded, meaning I can discard the card and a drone to repair up to 2 instead of 1 damage to my hull? Or is it that I can discard regeneration sequencers and a drone at any point to repair up to 2 damage to my hull?
Whenever one of your upgrades is discarded, repair 1 hull damage. Or, you may discard this card and spend a drone to repair up to 2 damage to your hull.
