If there's a 'fix', it won't be aftermarket. The noise is the ratchet inside the motor.

I'd rather keep my phone in my pocket/pack, safer from the vibration and impact.
I'd get a Garmin 130, or higher, depending on the features I'd use.

It's the ratchet inside the motor - nothing to worry about.

Cube's website says Tour+ is available. It may not come standard and you could still have the original Tour mode.
Cube's Canada site states the modes are Eco, Tour ("Steady support for long tours"), EMTB, and Turbo - so you could have the original Tour mode, which is 140%.
"On flat terrain, Tour+ mode down-regulates the motor to the level of Eco mode to save energy. On steep climbs, it adapts to the rider’s performance and offers support up to the level of Turbo mode."...
I don't know if the 2022 Treks come with EMTB Lite or TOUR+, so here are all the modes:
Percent Assist:
TURBO: 340%
eMTB: 140-340%
eMTB Lite: 140-250%
TOUR: 140%
TOUR+: 60-340%
ECO: 60%
Maximum Torque:
TURBO: 85Nm
eMTB: 85Nm
eMTB Lite: ~65Nm
TOUR: 50Nm
TOUR+: 85Nm
ECO: 40Nm
The new TOUR mode is probably TOUR+, whereas TOUR on your 2021 it could be EMTB Lite. I've found EMTB Lite to be better for battery life, as the assistance level doesn't ramp up as far as TOUR+.
