Does it matter what I set "allocation unit size" to when formatting an SSD?

My SSD is already formatted and has the default allocation unit size of 4kb. Will this option affect my SSD's lifespan in any way? I heard from someone that having the allocation size different from the SSD's actual block size will decrease it's lifespan by increasing it's amount of writes. According to Minitool, my SSD's partitions are aligned. This is all that matters right?

I have a 250GB 850 EVO. According to some website, it's block size is 1536kb
