Thank you for your reply, and for letting us know your "ghost" alarm is a regular daily alarm / reminder / alert.

Sorry no-one yet has come up with a solution for you.

Could a paired Apple Watch be the alarm source ?

or

If you could identify the particular alarm sound/ ringtone ...

maybe the source (audio file?) of that particular sound could be somehow deleted./ removed from iPhone,

or replaced with a blank-silent audio file ?

All the best :-)
