Whether the console firmware supports it is not confirmed yet.
The VAXstation 4000 series is difficult because these use the SPX and LCG graphics controllers for which there is no documentation available. I've been able to work out some of the details by looking at driver source code but that only tells part of the story. I have a HSC70 simulator which is just about (with a lot of manual intervention) able to boot the CRONIC operating system, but there are no CI, SDI or STI adapters implemented because almost no documentation is available. I'm guessing the manuals that are needed are: EK-HS572-TM - HSC50/70 Software Technical Manual EK-HS574-TM - HSC50/70 Chip Description Technical Manual However I've seen post from various people over the years asking for these manuals but no replies so they are most likely lost for good. Also I could do to obtain the ROM image from a real HSC70. It would probably be easier to just write an MSCP server that hooks into the virtual CI.
