Undici.ProxyAgent never verifies the remote servers certificate, and always exposes all request & response data to the proxy. This unexpectedly means that proxies can MitM all HTTPS traffic, and if the proxys URL is HTTP then it also means that nominally HTTPS requests are actually sent via plain-text HTTP between Undici and the proxy server.
The product does not validate, or incorrectly validates, a certificate.
