Bigger chainring = higher top speed! Have you had any problems? Bosch Gen3

He folks,
Ok, So I have a Cube Acid One hybrid 2020.
It has the 65nm gen 3 motor from bosch fitted.
I am travelling mostly on country roads and I'm mostly in the higher 3 gears.
At top speed like 28mph (thanks to road tyres being fitted), I feel as if I can go faster but I'm just spinning out.
So I am thinking of installing a bigger chainring upfront So I not only will start to use the higher gears more but will also get a better top speed.
I was just wondering if anyone here has changed the chainring with a similar bosch set-up with no hassle whatsoever?
The last thing I want is to go through all the hassle of changing the front chainring then the CPU to spit out an error message and shut down!
P.S. It currently has a 38t chainring and an 11-36 cassette.
I have a speedbox 3.0 fitted with no problems whatsoever.

No idea but if you think it will fit then try it. The electronics won't be affected.
A mate wanted a larger chainring on his gen 4 bike but the design meant it would have hit the swing arm.
