Is it possible to add and remove criteria on the fly with dapper? I need this to implement user driven filtering. It is not feasible to have a query for each filter as there are too many combinations.

At the most basic level, you can just build the TSQL dynamically in a StringBuilder – adding extra
and c.Name = @nameetc . Don’t worry about extra parameters; send them all – the library inspects the command and doesn’t add any parameters that obviously aren’t used. There is a second, newer API for this specific scenario, but I can’t remember the specifics without checking (and I’m not at a computer). I can try to add more details later (assuming Sam doesn’t).
