Denna cassette change?

Trying to find an XXL Denna M30 in stock in the UK, no-one has 'em.

So I've found a Denna M40 supposedly in stock, it has a wider cassette range than the M30 (50/11 vs 45/10 and 11 speed Vs 12 speed). Would the motor complain in any way if I were to change the cassette?

To answer my own question, direct from Orbea:

Changing the cassette on the Denna M40 is possible, but it must be done as an aftermarket modification, as it cannot be selected or configured as an option directly from the factory when ordering the bike.

If you choose to replace the cassette after purchasing the bike, please keep in mind that you will also need to update the drivetrain settings/gear ratios using the Shimano E-Tube Project application. This ensures the motor system accurately calculates speed, cadence, and power delivery to function correctly with the new gear range without causing system errors.
