Yesterday I checked
records.ru and there isn't a data record of a release of Ivanov conducting Sym 11. The website is a thorough though granted not entirely complete database of Russian records. Ivanov conducted a few smaller works by Shostakovich.
It is possible, of course, that the recording was not released until now, or is so rare that there isn't a record of it online.
Last year I uploaded a video of Ivanov conducting Rachmaninoff's PC 2 with Rudolf Kerer.

Not that it necessarily means anything, but one listener went out of his way to comment -- 'very bad conductor'.
I don't have it with me, but from the same concert there's a video of Ivanov conducting Tchaikovsky's 1812 Overture.
