  We have investigated the impact of Ru substitution on the multi-band
electronic structure of FeSe$_{1-x}$Te$_x$ by means of angle-resolved
photoemission spectroscopy (ARPES). The ARPES results exhibit suppression of
the $xy$ Fermi surface and the spectral broadening near the zone boundaries,
which can be associated with the lattice disorder introduced by the Ru
substitution. The degeneracy of the Fe 3$d$ $yz$/$zx$ bands at the zone center,
which is broken in FeSe$_{1-x}$Te$_x$, is partly recovered with the Ru
substitution, indicating coexistence of nematic and non-nematic electronic
states.
