Hi @atray13 ,
Do you want to show option set field as radios in gallery?
Like the screen shoot:

If so, I 've made a similar test for your reference:
1)in my test, my entity named: testmanies, my option set field named 'ExpenseStatus ', my custom option set named test123
2)insert a gallery, set its Items:
testmanies
insert a radio button inside the gallery, set the radio's Items:
Choices(testmanies.'ExpenseStatus ')
set the radio's Default:
ThisItem.'ExpenseStatus '
Then the radio will display the option set field.
If you want to use this radio to update option set value, you could use formula like this:
Patch(testmanies,ThisItem,{'ExpenseStatus ':Radio1.Selected.Value})
Then the radio will be used to display and update this option set value.

Best regards,
