It seems `org-anniversary' supports %d for year and thatʼs about it,
which is not surprising, since itʼs just a wrapper around
`diary-anniversary'.

How about:

diff --git a/lisp/org-agenda.el b/lisp/org-agenda.el
index 78fe13303..9049b3a42 100644

(Iʼm guessing yet-another-config-variable is unnecessary)

Itʼs working fine for me in org-9.3.6. Note that I have my default
agenda view set to a fortnight, and those dates span two different
weeks.
