OK, found the problem.
 
To achieve my objective, the right approach is to add “AGPL-3.0” to INCOMPATIBLE_LICENSE.
This causes the build to fall back to the older version of db.
 
However, I figured this out after finding the following line in poky/meta/conf/distro/include/default-versions.inc:
 
                PREFERRED_VERSION_db-native = ${@incompatible_license_contains('AGPL-3.0', '5.%', '6.%', d)}
 
Is it correct that this is an absolute assignment rather than a conditional one? I think my
PREFERRED_VERSION_db-native assignment would’ve worked if it hadn’t been overridden
by this one.

its a distro policy based upon licensing if weak assignment is used then the licensing  won’t be able to enforce the decision
if someone overrides it.

Subject: [yocto] PREFERRED_VERSION for native package
 
Yocto Fido
 
I am trying to use PREFERRED_VERSION to select an earlier version
of the “db” package. The build includes both db and db-native variants
of the package.
 
I set PREFERRED_VERSION_db variable and this successfully changes
the version of the db package but not the db-native package.
 
I tried also setting PREFERRED_VERSION_db-native but this doesn’t
seem to have any effect.
 
What am I missing? How can I override version for a native package?
