You may try to override 99-default.link with

[Link]
NamePolicy=

As I understand, having another file earlier in sorting order should do
it as well.

This should effectively disable name generation. Unfortunately, as
opposed to units, it is not possible to selectively override specific
key - first matching rule file is used entirely. This could lead to
missing changes in default link file on updates.
