Fundamentally there's nothing special to system.multicall, while it can have dedicated support in the library (as in python) it's not necessary.

It does need to be implemented in the server, but aside from that it's just a regular function which takes an array of {methodName, params} structs, and returns the corresponding responses array, where each response is either the result of calling the method, or a {faultCode, faultString} struct.

So yes, if the server you're accessing supports system.multicall you can call it by crafting the multicall by hand.
