Could work. I don’t know how your specific SSD handles partitions. Some SSDs don’t care about partitions on the physical level at all. In that case using a partition or unpartitioned space to reserve space to stay empty would work.

Some SSDs might actually physically reserve space for a partition, in that case leaving something unpartitioned or as an empty partition wouldn’t help.

I think most SSDs should ignore the partitions on the physical level, so it should work, but no guarantees.
