Is there any practical benefit to changing the NVMe sector size?

Here is some information relevant to my case.

❯ sudo fdisk -l /dev/nvme0n1

Disk /dev/nvme0n1: 465.76 GiB, 500107862016 bytes, 976773168 sectors

Disk model: MSI M450 500GB

Units: sectors of 1 * 512 = 512 bytes

Sector size (logical/physical): 512 bytes / 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes
