I think so, here is what I found just on wikipedia : (and read nothing about a rule not permitting one hand for the clock and an other for pieces)
https://en.wikipedia.org/wiki/Rules_of_chess :
Under "4 Equipment" :
Before the start of the game, either the arbiter decides, or whomever is playing Black, where the chess clock is placed.
Under "3 Competition rules
3.1 Act of moving the pieces
3.2 Touch-move rule" :
(Maybe read it for other things...)
Nothing relevant here :

https://en.wikipedia.org/wiki/Time_control
I'm right handed and would like the clock on my right side. Also, can I move the pieces with my left and press the clock with my right hand simultaneously to save time? Any rules regarding these?
