is there any way todo this ?

Hay, I got UE_5.1 installed on my laptop and created My Metahuman in the 5.3 version so is there any way to get that 5.3 metahuman into UE 5.1?

I can upgrade UE 5.1 to 5.3 but my laptop is getting overheated so I can’t is there any way beside this?

the short answer is “NO”
starting with Meta Human for Unreal Engine 5.2 there were several changes made to the Meta Human system that directly from Quixel “Breaks Backwards compatibility with UE 5.1 and before” MetaHuman Versioning Guide

that being said there is a potential for “good news” where there is a version selector in the Meta Human creator where 5.1 should be an option.

additionally most of the changes made to Meta Humans for 5.2+ were on the Rig, so you can create a meta Human for 5.1 with the general proportions similar to the Meta Human in question, then get the Maya project files for both (this is one of the export options), and place the Rig for the 5.1 Meta Human bound to the Meta Human at issue (the one made for 5.3)

** as a side note you might be able to do these actions in Blender which can import Maya project files, though “millage may vary”
