Specifically to your question, your bicycle's bottom bracket will define the crankset type (GPX, BB30, BSA...) - not your groupset.
However, when upgrading cranksets you need to also consider a number of other factors like derailleur capacity.
The Alivio groupset supports 3x and 2x cranksets, according to the Shimano product page: https://bike.shimano.com/en-AU/product/component/alivio-m3100.html
The rear derailleur Alivio RD-M3100-SGS has a total capacity of 45T so keep that in mind when selecting the chainring sizes (More details here)
