Use a live Linux ISO that can run entirely in memory, and run step 3 in an infinite loop. Take the USB with you and leave the PC running.

Step 1: Back up important files
Step 2: boot from live Linux USB
Step 3: dd if=/dev/zero of=/dev/nvmeX && dd if=/dev/urandom of=/dev/nvmeX Repeat

Write random data in the drive over and over again, with one or two pass there are some sophisticated techniques that can get some sliver of data out if the random. But with 3 4 passes and more it’s statistically unlikely they can recover anything.

This, but encrypt the backed up data with full disk encryption.

If you have nvme use secure erase first.
