(None) Value on Sharepoint List

Hello all!

I created a list in Sharepoint where one of the columns looks for values from another column.

I'm using this list in Microsoft Teams to be populated, but when I select the corresponding column field, the first option that appears is (None).

This field is required, but is it possible to remove this option (None)?

Even if someone tries to select this option the list warns that "You can't leave this blank", but I still would like to remove this option.
