Uber Last trip issue

When I drive Uber and I am on my last trip of the day is there a way I can tell Uber it is my last trip and not send me any more requests?  I hope there is a way, because when requests come in and I don't take them because this is my last trip it really hurts your acceptance rating.  That acceptance rating is crucial to Gold and Platinum statuses.  Last night I drove 16 rides.  On my last ride of the day I got 5 ride requests that I didn't accept and it killed my rating.
