Is there a way to point numba to the latest version of the TBB installed on my virtual environment, please? By default, numba finds an outdated version of the TBB and resorts to OMP.

Here is the numba warning:

NumbaWarning: The TBB threading layer requires TBB version 2021 update 1 or later i.e., TBB_INTERFACE_VERSION >= 12010. Found TBB_INTERFACE_VERSION = 10003. The TBB threading layer is disabled.

Although the installed version of TBB is:

You can try by setting the "TBBROOT" environment variable to the path where the latest TBB is installed. Numba 0.54 will support TBB 2021, please check your Numba version.
