The virtual_alias_maps does not know if the address is local or
not. Its behavior will not depend on that.

If you say "I'm serving only the following virtual domains; ignore
those entries in virtual_alias_maps that don't match it", then that
is exactly what the "domains" feature in ldap_table(5) does.
If that is now what you want, then you need to be more precise.
People often don't say what they want, so I will take the liberty
to assume that you want the following solution.
If you need to exclude some local domains only in the Postfix SMTP
server, then you can specify an alternate LDAP client.
/etc/postfix/master.cf
smtp .. .. yadda yadda ... smtpd
-o virtual_alias_maps=$smtpd_virtual_alias_maps
/etc/postfix/main.cf:
smtpd_virtual_alias_maps = ldap:/path/to/file
path/to/file:
# Filter based on inclusion:
domains = domain1, domain2, domain3
You can also use an approach based on exclusion:
domains = !example1, !example2, static:all
