Is it possible to set up a yf Windows Openvpn client without certificates?

Question

openvpn

Hello.
Such a task is to configure openvpn to our router from one computer so that it can be seen from our network. On that computer, everything is blocked, access is only through a proxy. I made a redirect to port 22 on my router, tried 80, 443, still does not connect. The connection goes through a proxy and rejects the certificate.
Can this be bypassed somehow?
As an option, to either connect from Windows to Windows without a certificate, or from Windows to Mikrotik without a certificate, or some other options?
I am attaching the connection log.

1. Disabling certificates is a bad idea.
   What is said below is probably not relevant to the case. Just as a note.
   I don’t know how the situation looks now, but earlier Mikrotik with OpenVPN had limitations. UDP was not supported and in my opinion it is impossible to use ta keys. Since then, I have only used flashed Mikrotiks.
