Hello 
When this EXPERIMENTAL: preconnect and dns-prefetch resource hints for CDN doma… · discourse/discourse@36cdb14 · GitHub site setting has been available I enabled this on my site. After then this commit has been changed to global settings here DEV: Consolidate experimental 'Link' header implementations (#26377) · discourse/discourse@1cc8c72 · GitHub
I’ve enabled the GlobalSetting early_hint_header_mode preconnect but I see there is an other GlobalSetting early_hint_header_mode prefetch. Is that possible to enabled both or maybe am I misunderstood something. 
Thank you
