If you have an under-the-floor crawl space, you could probably bring

cut out an opening and flush-mount a box with RF connectors in it.

Google "plenum wire" to find what kind of cable is required when using
plenums for any kind of electrical wiring (similar issues may apply
to other plastic materials as well).

Normal insulation can generate toxic fumes in the presence of heat from
a fire, capable of killing or incapacitating the occupants even before
the fire itself threatens them.

That doesn't apply when you run one or two coaxes through your own home.
There are more than enough things in your house that generate toxic
fumes when burnt to make those few metres of coax insignificant in
comparison.

It certainly does apply if the coax is actually run through a plenum space. Some homes use joist channels as return air plenums and any cable that passes through such a space must be plenum rated or otherwise protected. That said no one has said that is what is happening in this case.
