What do you mean by "disable"?  If you mean force Emacs not to show
any glyph there, then there's no way of disabling that completely.

Yes, and that's by design.

I don't agree that they are clutter.  They serve as a clear indication
that the line was truncated.  Since Emacs supports a feature whereby
only the current line is hscrolled, this indication is important.

I'm not interested in adding a feature that would disable these glyphs
on TTY frames.  (On GUI frames, Emacs does not show these glyphs by
default, and the continuation/truncation indications are shown on the
fringes.)
