"Your fanged bite is a natural weapon, which counts as a simple melee weapon with which you are proficient"
"Enhanced Weapon: Item: A simple or martial weapon"
As such, dhampir should be able to infuse their bite attack Which would make it also qualify as a magic melee weapon, for purposes of pact of the blade for warlock
The dhampir's bite attack technically should count as equipment for these purposes.
Currently, you cannot on dndbeyond use infusions on the dhampir bite attack, despite it being a rules legal target.
I was inspired by this post, which goes step by step why infusions should work on natural weapons, particularly the dhampir bite attack
