How to Remove the "All Others" Value from Vehicle Type List of Values

For all vehicle mileage expenses types there is a vehicles type field that appears on screen with two options within a list of values

• All Others
• The actual option they have chosen such as Bicycle, Car/Van, Motorbike, E-car

Is there a way of removing "All Others" as it just doesn't work, it doesn't calculate a value and I cant see what the point of it being there is

Alternative is there a way of disabling the vehicle type field, we have all of our different vehicle types split out anyway so the claimant will have already indicated what mode of transport they are using?
