Is there an equivalent of RegQueryInfoKey for Windows Kernel Mode Drivers?

Is there an equivalent of RegQueryInfoKey for Windows Kernel Mode Drivers?

I am currently investigating writing a windows kernel-mode driver, and in
terms of registry access, I found RtlQueryRegistryValues on MSDN. However,
while RtlQueryRegistryValues is good for querying actual registry values,
I was wondering if there's a registry function for determining the number
of subkeys of a given regkey? Again, I found RegQueryInfoKey on MSDN, but
my understanding is that it's for user-mode applications. Is there an
equivalent function for windows kernel-mode drivers?
Thanks.
