I'm not sure if you've seen these already but here are some resources for IE mode:

• To set up IE mode:  Getting Started guide
• Guided experience in the Microsoft 365 admin center to help configure IE mode: Discover and configure sites for IE mode guide

If you need additional help with deployment or configuration assistance for Microsoft Edge or
