How to check and change regional settings for local users in windows?

Question

PowerShell

Colleagues, good day to all!
I'm not a windows/powershell expert at all. But now I have the task of checking, and if necessary changing, the regional settings for existing and new local windows server users. We use ansible to manage users and settings for our software, users are created to run sites in IIS. For a number of reasons, we have a situation where users are created with incorrect regional settings, and we are tedious to check and edit the settings for them.
My question is: how, preferably, powershell, to change the regional settings for already created users?
PS The servers have admin rights. The situation with the crooked creation of users is a legacy problem in the organization of the development process. This also applies to "copy settings for all new users"
PPS options for group policy, domain and other things are not considered.
