I would like to know how I can set the "people picker" field to be non-required.
I tried to use advanced settings to set non-required but it isn't worked. Someone know how to fix it?
Edit column and uncheck "Requirement that this column contains information". Would this fix the issue? Also have a try to change a browser or clean browser cache if the issue persists.
Try below approaches:
Modern experience:
Go to your SharePoint list
Click on person or group column header > select Column settings > select Edit:
Click on More options in column settings panel at the right side
Set Require that this column contains information to No and click Save button.
Classic experience:
Go to your SharePoint list
Click on Settings (gear) icon at top right corner > select List settings
Scroll down to Columns section on list settings page and click on the person or group column name. It will open column settings page
On column settings page, set Require that this column contains information to No and click OK button at the bottom of page:
