by following the steps below:

• Click Start, then go to Settings >
  Projecting to this PC.

Enable PIN entry for Miracast wireless mirroring via WiFi Direct

I am looking for possible solution to enable PIN entry upon every Miracast connection between PC to Miracast Receivers.

Based on Miracast Mirroring protocol, PIN authentication is only possible if connecting Miracast over MS-MICE. For Miracast over WiFi Direct, the PIN entry will only occur during the first connection, and Windows will cache its PIN from subsequent connection onwards until the laptop or Miracast receiver recycle its power.

If I want to enable PIN entry on Miracast via WiFi Direct, does Microsoft has any hidden Registry configuration to allow users to enter PIN on every Miracast session?
Is there any possible solution to work around this Microsoft behaviour in not caching the PIN?

Any suggestion will be appreciated.

My laptop is running on latest Windows 10 Pro 21H1 version Build 19043.1023.
