NL 100 - 9 high flush on turn with two players all-in before me

Have to call and hope one with Ace and one with lower flush?

Reads: SB is complete donk and button is solid player.

fold. if button is solid he doesnt have a worse flush here ever.

pretty easy fold here unless u have reads that these 2 players are complete and utter donks and would call with kk or something retarded here.

Is it unreasonable to put Button on a high ace and shoving to charge for drawing to a fourth diamond?

SB is a complete donk who I can easily put on ace rag. Does this (likely 'bloated' pot) make calling at all closer?
