No. For god's sake, fix whatever components you are using that think
they must have 9.6.0 rather than 9.6.later. Read the release notes [1].
Insisting on 9.6.0 four years later is professional malpractice.
(I'll not even get into the question of whether you should be installing
some later release branch than 9.6.x; but I can't help noting that 9.6's
EOL is 11 months away.)
