No, on long time controls, humans cannot see enough of the tree in some positions. They might be able to push the game sometimes into a position where they can hold if the engine is not set up to prefer complicated positions.

But

This is one of my favorites. On extreme short time controls, humans can handle some really good engines some of the time! Here you have Andrew Tang beating Leela in hyperbullet: https://youtu.be/Wf-wFXRpwgo

Another approach that sometimes works is to be really booked up in dubious lines with an engine that does not have too much time, something Jonathan Schrantz manages from time to time https://youtu.be/FC2P6VUYu78

It's a little debatable whether Andrew Tang counts as "human" when playing hyperbullet chess.
