If you're using FSUIPC7 (MSFS) and the new MSFSVariableServices class then yes, you can: 

MSFSVariableServices.CreateLVar("L:NewLVar", 0); // (Name, Initial Value)

If you're using FSUIPC6 (i.e. the legacy FSUIPCConnection.ReadLVar() method) it's possible (FSUIPC6 supports creates) but I haven't included it in the DLL. Let me know and I can a add it.

For FSUIPC5 and earlier versions it's not possible to create LVars.

Hello,

i am using MSFS, but i did not know about MSFSVariableServices .
Can you pls give me a little tip how to use it in a C# project ?
Or is it in the FSUIPC description ? ( i am not home right now )

There's an example project that explains how to use it. It also explains where to get a required file called FSUIPC_WAPID.dll that you need, and how to include it in your project.

The example project is a few years old now. If it includes a FSUIPC_WAPID.dll file it could be too old to work so you should get the latest. On the MSFS side you need to install the WASM module which is installed by the FSUIPC installer. So make sure you're also up-to-date with the latest FSUIPC7.

MSFSVariableServices is a completely separate system from the normal connection used for offsets.

It's the preferred way to work with LVars (and HVars) in MSFS as it's hundreds of times faster than FSUIPCConnection.ReadLVar().
