yes, it could be obtained through the Developer Program (I have a copy), though I seem to recall some strings attached.
There used to be an emulator from Stanford which could run IRIX 5.4 https://en.wikipedia.org/wiki/SimOS
Perhaps you mean IRIX 5.3, the last 5.x, which ran on Indy, Indigo, Challenge, etc, or 6.4 which was an early special for the Octane and O2000/Onyx2. There's no IRIX 5.4, at least, not released. It went from 5.3 to the very short-lived 6.0.1, then 6.2 (Indy, Indigo2, etc) 6.3 (first release for O2) and 6.4 (ditto for Octane, Onyx/O2K) and quickly to 6.5 across the product line.
