Change from class A to class C

Dear all.
It is possible to change a cubecell device from class A to class C for an specific amount of time, to listen for new messages and then go back to class A?
Or what could be the correct implementation to listen for example 1 hour/day for messages dedicated to my device ?

I am using Arduino IDE with LoRaWan_APP.h.
Thank you in advance.
Best regards!
