Conventional wisdom is that we should not defrag an SSD drive. The additional writes needed to accomplish the defrag shortens the drive life, and there is almost no speed benefit for data access to doing it anyway.

I just received a promotion for something called O&O Defrag Professional. https://www.oo-software.com/en/products/oodefrag

This has a free trial mode. The basic new idea here is that there is a new algorithm that is OK to use on an SSD, and is far more conservative than traditional defragging methods. The algorithm is called SOLID.

Try at your own risk. In my case, it took about 4 minutes to improve an SSD drive that was 11% fragmented down to under 1%.
