Mph vs kilometers/hour

i live in Canada. we use kilometers. my seadoo spark trixx 2019 displays mph. is there a way to change this myself?
I’ve heard that you have to take the machine in and pay for it to be done.
not a big problem, but wondering if there’s a way to change it myself.

As far as I’m aware, the dealer needs to do it. If you find something different, please update us!
