Dear Cristina @CristinaLavosi
Not possible with the current options atm, bit of a tricky one - easy to remove clicking altogether but obviously not practical!
there is the Swiper API, looking at click events: https://swiperjs.com/api/#events
Also preventing click but not drag is a thing to google: https://stackoverflow.com/questions/18032136/prevent-click-event-after-drag-in-jquery/18032193
https://stackoverflow.com/questions/53703120/how-can-i-prevent-click-on-drag
But at the moment this may not be an option, unless asking the aid of a developer.

Sorry that this is not the help you were probably after - hopefully others have some ideas, if too difficult compromising on that area of your design may be necessary
Best wishes for 2021!
