OCSP validation of client certificates

[nginx_developer]

Hi Forum,
       I see that nGinx supports configuration to perform OCSP validation of
server side certificates and staple the validation response to the client.
My question is whether nGinx supports OCSP validation of client presented
certificates. 

I seem to hit a dead end with documentation for that question. Would be
helpful if someone could answer this. 

Thanks in advance for your time.
