Can I play all 88 keys from a M32?

I am not sure if I understand the question correctly , because : are you not just supposed to use the 'Transpose Buttons' for any octave change ? Ref. : 6.4. Transpose Buttons , Page 34 : https://www.native-instruments.com/fileadmin/ni_media/downloads/manuals/komplete_kontrol/KOMPLETE_KONTROL_M32_Manual_English_28_10_2021.pdf

Else , I am not sure if the "the MIDI Assignment Editor" can help you achieve you anything ! ? Ref. : Page 59 : https://www.native-instruments.com/fileadmin/ni_media/downloads/manuals/komplete_kontrol/KOMPLETE_KONTROL_M32_Manual_English_28_10_2021.pdf

Maybe you can also control the midi keyboard from inside a DAW ? :
