If you can push something you could say it is pushable. What do you say about something which you can enable and about something which you can disable?

Capable of being enabled and capable of being disabled, and for something which you can troll, you can say capable of being trolled.
(And no, I did not add that to Wiktionary just now.)
A toggle is generally recognized as being a binary condition, one or the other. I think it is a nice fit for capable of being enabled and disabled.
You could also use switchable, but it does not have as strong of a connotation for binary states and would cause more confusion.
