Asbestos cement sheets indoors before renovation, what to do?

[Jorpen95]

Hello,
Last year, we bought a house built in 1959. Currently, we have a laundry room that is connected to a storage room (old boiler room). We are planning to build a bathroom in the laundry room and turn the storage room into a utility entrance/laundry room. I haven't previously thought much about whether it might be asbestos cement on the walls, assuming instead that it's a thin fiberboard.

Yesterday, I sawed an inspection hole and quickly realized from the characteristics of the board that this is most likely asbestos cement. It's used on both the ceiling and walls, probably for fireproofing. See picture. What are your thoughts?

Now to my question about how to best handle this for renovation:
1. Is it possible to frame directly on the boards and then sheet over it? Legal/illegal?
2. Must all asbestos cement be removed, not to be enclosed under any circumstances?

Option 1 would be significantly simpler, as option 2 involves a lot of demolition for pipe fittings, pipe hangings, etc.

Thanks for the response,

Spontaneously, it looks more like a wood fiberboard, looks very yellow to be asbestos cement? The backside, however, resembles an asbestos cement board.

Spontaneously, it looks more like a wood fiberboard, looks very yellow to be eternit? However, the back side reminds me of an eternit board.

Yes, that thought about the color crossed my mind as well, tried to google a bit. As far as I know, wood fiberboard is somewhat flexible, this board is rigid and resembles the sound of thin roof tiles when you place them on the floor.
