Is there any way to enable external sharing for the tenant-my.sharepoint.com domain with Sharepoint Online?

Question

I want to enable external sharing for the tenant-my.sharepoint.com domain so that external users can see people's profile pictures, which are stored at https://tenant-my.sharepoint.com/User%20Photos/Forms/Thumbnails.aspx?id=%2FUser%20Photos%2FProfile%20Pictures. Right now, external users only get the default anonymous grey faceless picture when profile pictures show up, and when they try to open the profile picture in a separate tab, it says that external sharing is disabled for the image.

Answer 1

Go to SharePoint admin center-> site collections, choose the site collection https://tenant-my.sharepoint.com and click sharing.
