Is there any time travel in the MCU
aside from the time travel that the Avengers use in Endgame to undo the effects of Thanos' snap?
In Doctor Strange, Strange has a time loop that resets the entirety of the Dark Dimension. Effectively, this sends him back in time, but since it doesn't only affect him and resets his physical state as opposed to leaving it unchanged, it's not conventional.
Similarly, being able to see the future, as some of the sorcerers can do, might be considered a form of informational time travel.
Agents of S.H.I.E.L.D. had a extended time travel plotline involving the Kree in its fifth and most recent season, presumably as part of the tie-in to Infinity War.
Runaways had a message sent back to the past (informational time travel).
Thanos reversing time so that he could get the Mind Stone from Vision's head. He travels into an alternate version of the past when he does that.
