How to remount a disk that goes into read-only mode without rebooting?

I have a kernel bug that makes my SSD go into read-only mode. To fix this I have to reboot the system, do fsck /dev/nvme0n1p2, and then reboot again to make everything work.

Instead of doing the reboot, I tried to just do

sudo fsck /dev/nvme0n1p2

but how can I mount the nvme0n1p2 disk without rebooting? I want to work on my machine without needing to reboot.

I tried:

lz@blade:~$ sudo mount /dev/nvme0n1p2
mount: /: /dev/nvme0n1p2 already mounted on /.

So I tried:

lz@blade:~$ sudo umount /dev/nvme0n1p2
lz@blade:~$ sudo mount /dev/nvme0n1p2
mount: /: /dev/nvme0n1p2 already mounted on /.

Can somebody help me?
