How can I use the LD_PRELOAD trick on Windows to circumvent MKL performance degradation on AMD CPUs?

How can I use the LD_PRELOAD trick on Windows to circumvent MKL performance degradation on AMD CPUs?

The documentation linked here explains that the LD_PRELOAD trick can be used to force MKL to use the best performing routines by bypassing the CPU check that defaults to inferior routines on non-Intel processors.

How can I achieve this on a Windows system?

PS: MKL_DEBUG_CPU_TYPE=5 trick When you have an AMD CPU, can you speed up code that uses the Intel-MKL? cannot work anymore for Intel compiler distribution 2020 and and newer.
