.NET 3.1 sdk alternative for UE 5.0.3

Hello. Im unable to create solution files for my project because it requires .NET 3.1. Unfortunately my company has rejected the use of this and will only accept newer versions only. Is there a way I can use 5.0.3 with any of the newer NET.sdks and if not, does 5.1 or 5.2 still require 3.1. Many Thanks
