ᐅ Uninsulated sloped ceiling. Is it possible to add insulation later?

ChrisReHello everyone,
I have an older house where unfortunately the sloped roof areas are not insulated. This means there is no insulation between the rafters. However, the inside is already covered with plasterboard carrier panels and properly plastered. I recently took the time to remove all of this on one slope, then installed insulation, covered it with a vapor barrier, put up drywall, filled joints, sanded, applied textured paint, and finally painted. This whole process unfortunately took a very long time, as I could only work on it after my job.
Since all the other walls are actually very well plastered on the inside, I would like to solve the insulation on the other slopes differently if possible.
Now my questions:
Is there an insulation material that I can add afterwards by pouring or blowing it into the cavity? What about the vapor barrier in that case?
The space between the boards of the roofing felt and the interior cladding can be accessed from the attic. It needs to be filled with this material to about 16 cm (6 inches) in height if possible.
I know there is loose-fill insulation granulate used for floors, but how does that work with the vapor barrier? I would be extremely grateful if you could help me here.
Many thanks in advance for all your answers.

Cellulose insulation comes to mind. It also releases moisture back into the air.
Alternatively, you could contact a company that specializes in blown-in insulation.
If there is actual roofing felt under the tiles, I would recommend going for 14cm (5.5 inches) to ensure proper moisture transport.
