Windows Cuda silent installation to non-default path


I am trying to silently install selected packages of the Cuda Toolkit from the Windows command line.
However, I must choose a non-default install path (i.e. C:\Programs Files… is not suitable for me) and it seems I’m not able to find a command line switch to get this.
I have tried to specify the install path as a first parameter in the command line:

cuda_10.1.105_win10_network.exe C:\my\install\path -s package1 package2 …

but it does not work, the installer exits without doing anything.
Also prepending the install path to each package name does not do it.

The install documentation does not mention this case and it seems I cannot find it even in this forum.

Any suggestion would be greatly appreciated.
Thanks for you time!
