How to enable different users to edit different sections of a List form?

Hello jamjar01

in SharePoint list form it's not possible to give permissions on fields. And in list form editing it's limited to show/hide fields based on permissions or rules: https://docs.microsoft.com/en-us/sharepoint/dev/declarative-customization/list-form-conditional-show-hide

For your use case i recommend a Power Apps form, in there you have more possibilities to give teams the right view, based on rules you can use activ/inactiv controls or you can hide/unhide fields:

Hope this help.
