In the UK this part of Rule 14 applies:
(4)Subject to paragraph (5) a flying machine shall move clear of the landing area as soon as it is possible to do so after landing.
(5)Paragraph…...(4) shall not apply if the air traffic control unit at the aerodrome otherwise authorises the flying machine or glider.
ie. if nothing heard: vacate a.s.a.p, which is what ATC will be expecting.
There's nothing to prevent you asking ATC before landing if you may roll to a particular exit. There's also nothing to prevent ATC asking you to roll to a particular exit.
