Remove and reinstall parquet

[Mandelitomamma]

I live in a single-story terraced house with a concrete slab, sills, insulation, and wonderful oak parquet, built in 1959. It's drafty and the floor is cold but, as I said, very nice. Now a rat has died under the floor, and it smells terrible! Anticimex has put out poison in the gardens, and they say it takes "only" 6-8 weeks for the smell to disappear. However, I've read on various forums about odors that linger for up to a year.
We are three people who now have to study/work in a two-room and kitchen space because two rooms cannot be used due to the stench.
Now to my question; I see here that some have reused their old parquet flooring. Can you lift parts of the floor and then put it back, or do you have to remove the entire floor and start over, so to speak? I have a fairly certain idea of where the rat is, and could potentially lift the floor in a limited area. Provided that it can be put back again.
What do you think? Does anyone have any good suggestions?

I think it's very difficult to remove and replace it with a good result, at least as a layman.
A former boss tore up nearly 100sqm of parquet that was wet, let it dry, replaced it, sanded, and lacquered it, but he has +40 years of experience.

Is the rat in a room or in the middle of the living room? Does it make sense to saw an opening just big enough to get down and fix it neatly??

I’ll probably have to ask a professional for help, definitely. But I saw in previous threads that several seemed to have succeeded in moving flooring to another room, so I was mostly wondering if it would work to take up just parts of it and then put it back, without having to take up the entire floor.

It's in one part of the room, about 1 m from the walls. The room is about 22 sqm.
