Grove AI Hat for RPI and Maix FPIOA

Hello I was wondering I have both the Grove AI Hat and a Maix Bit, the GAIhat has the grove sockets set up for different purposes while the Maix Bit has this FPIOA as they call it where each pin can be mapped for many purposes. So my question is, are the different grove sockets on the GAIhat fixed or can they be remapped like the FPIOA on the Maix?
