checkout process in cache ?

We are on prestashop 1.7.6 and use the Litespeed module. Everything is working fine but I am wondering if it is possible to cache the shopping tunnel with cart, address, carrier, etc. ?
I see that on all these pages there is no notion of miss or hit. Can we do something on these pages there or on the template so that some of it is cached? Thank you for your help and advices
