Structure for PTC graphene and tile

I have linoleum as a substrate and I don't want to pull it up. At first I figured floor level compound and ditra, but the guides say no to the primer and leveler on lino, stating the glue beneath will let loose.

If I go cement board for a backer, what's the thinnest and cleanest option for this form of install? More so how do manage the hazard of gouging or destroying the Graphene while effectively bounding the backer board to the lino and 1/2 ply substrate?

TIA for input!

    Real honest to gosh linoleum? If so, that guide is right. The glue holding the linoleum material and its backing (usually jute) to the subfloor is very weak. Further, there are very few adhesives of any kind which adhere to linoleum. I've hit this sort of problem from time to time, and the best options for flooring over old or damaged linoleum which can't or shouldn't be removed (usually historic value) are floating floors -- but that won't do for radiant.

    Doesn’t older version contain asbestos. So sanding it to get a rough surface may not be a good option. Is it over a concrete slab, or wood?
    Maybe visit some of the tile online groups, TCA, etc

    I had it tested for asbestos, hence why I don't want to rip it up. Can't sand it, same issue. It's over top 5/8 plywood
