@Saideep - a Choice column returns a single column Table.
I think what you mean is that you want to Filter out a specific Choice from a Dataverse Choice table, rather than Delete a Choice from the Choice table (whether it is a Global Choice or Local Choice).
Note the syntax for the Choice column name is dependant on whether your Choice column is a Local or Global Choice. You can quickly obtain the syntax by simply adding an Edit Form control into your App with the Choice column added as a DataCard, then click into the Items property of the automatically generated Combo Box control to obtain the Choice name.
For a Combo Box control, you can use:
ShowColumns(
Filter(
AddColumns(
Choices('Your Choice Column'),
"_Text",
Text(Value)
),
Not('Your Choice Column'.'Your Choice You Want To Remove' in _Text)
),
"Value"
)
For a Dropdown control, the syntax is much simpler:
Filter(
Choices('Your Choice Column'),
Value <> 'Your Choice Column'.'Your Choice You Want To Remove'
)
