If multiple price options exist within the same time slot but must be locked to a single option once a Ticket is booked, you can combine these two features to achieve that:
A Visibility Rule on your Variants, whereby no other Bands will be available once a Band is selected
A Basket Validation Rule that restricts the Customer from adding Tickets from more than one Band

This rule ensures that only one mission/Band can be added to a basket:
Repeat the above steps for the other Bands, i.e. create the same rule again with Heist Mission in the Only If section, and then again for Space Mission:

This means that the Customer won't be able to continue until they remove one of the missions/Bands from the basket
Once a Ticket from a mission/Band is sold, the only Tickets available for other players to book for that time slot will be for that one mission, as per the Visibility Rules that were set up:
