Default column choice value for dropdowns in a datacard Power Apps

Great for dashboards when the user shouldn't change the option but it still needs to be written to Dataverse or Sharepoint.

I put the card in DisplayMode.View so they cannot change it but it will be written,

LookUp(Choices('22-23-AthleticTrips'.pickupbuilding),Value="High School")

LookUp(Choices('List or Table'.YourColumn),Value="The Value you want")
