[MCU] Did Dr Strange willingly let himself get dusted?

So during Infinity War we saw Dr Strange get snapped away but I feel like he could have done a number of things to survive.

1. Astral Projection, we’ve seen him leave his physical body and turn into a ghost even while he was dead for that moment in his movie. We also saw the Ancient One as a ghost after she died from a failed surgery. 

2. Body Possession/Mind Transfer, now although is is mostly a comic thing I doubt MCU Strange can’t do it. I feel like if Strange wanted to he could of taken control of Thanos’ mind to reverse the snap and if he couldn’t do that then take control of Starks mind or at least just hang out in his subconscious for a while. 

3. Resistance, in an interview with the Russo Brothers they said that the reason Spider-Man lasted the longest was because of his will to stay alive. I think if Strange concentrated hard enough he could hold off the snap or at least until all of the other beings alive have died and the gauntlet focuses on him, enough time to tell Tony what to do without giving away the plan.

4. Healing Factor, another reason Peter survived for so long was because his healing factor was trying its hardest to slow the snap. All Strange had to do was put a spell on him the made him heal at an extreme rate.

Anyways let me know what you think because this has been on my mind for a while.

It is possible that all of the scenarios you mentioned existed in the 14 million possible futures Dr. Strange saw. The way it went down was the best way it could have gone, and anything he tried to do to change it may have either ruined it in unforseen ways, or in ways he saw and could not win using.
