Yes, you can deaden the noise somewhat.
I removed the bracket, enlarged the mounting hole, and added a
rubber grommet. Just make sure the grommet is a tight fit on the
relay. This did not eliminate the noise, but it did substantially
reduce it.

Subject: [TenTec] Comparisons of Relay noise in Ten-Tec Amplifiers
Hi all,
There has been a lot of discussion about the relative noise levels
of
relays in Orions and Omni VIs. Some complain that the relays are
too
noisy and others say they can barely hear the relay noise in their
rig.
I am interested in opinions on vacuum relay noise in Ten-Tec
amplifiers.
I own two Ten-Tec amplifiers, a Titan 425 and a Hercules II 420.
They
both have vacuum relays which appear to be the same type, and the
vacuum
relays switch in both amplifiers when operating QSK. My Hercules
II
vacuum relay is very quiet, and the Titan vacuum relay is quite
loud.
Since the relays appear to be very similar, if not identical, I
wonder
if I could quiet the Titan relay down to a noise level similar to
that
of the Hercules II, by mounting it differently. Are all Titan 425
vacuum
relays loud? I usually wear headphones anyway. When running the
Hercules
II I don't have to wear phones. When running the Titan 425 I have
to
wear them.
Thanks,
DE N6KB
