I've recently found an old to-do list of things to optimize an SSD. Some of them are definitely not needed anymore, while I'm not totally sure about others, so I'm going to list those where I got doubts here below:
1) Turn Off Indexing
2) Disable Hibernation
3) Disable ClearPageFileAtShutdown and LargeSystemCache
4) Disable Windows Search
5) Disable PreFetch and SuperFetch
6) Enable Write Caching
Hi, Indexing and Windows search has nothing whatsoever to do with SSDs.
On a correctly functioning system Windows search imposes no overheads and backs off (stops indexing) on even a small load. And it only indexes when theres been a change after the initial indexing.
So much mythology about Windows search remains from the days of Windows XP.
Disable Hibernation can be applied but many computers could be exposed to the risk of data loss.
So you would need to differentiate laptop from desktop.

Clearing page file is already disabled by default, it's only purpose is when you share your computer with other people because it may contain personal information.
Also enabling clear of page file is performance hit on shutdown.
Turning off indexing is bad idea because it will make your searches significantly slower, instead you should adjust indexing to index only files you really care about.
Disabling Windows search will make your Windows searches no longer work, you'll have to search your files manually.
Unless I'm wrong, PreFetch is no longer called like this, now it's sysmain service and there is no point to disable this, because it work only while system is idle, it does not affect your working time.
In short you gain nothing by these tweaks except less functional OS, and likely issues over long run.
Turning off indexing has no impact at all on an SSD, expecially if it's an NVMe drive. They're so fast that it just doesn't matter if there is an index; besides, if your SSD has DRAM, it already has a map stored internally that tells it where each file is located on the memory, so W10 indexing is completely redundant and would just waste some write cycles for nothing.
Disabling Windows Search you can still search within your system, it justs disables indexing and caching results. It may not be good to disable it if you also have HDDs in your system.
SysMain is the SuperFetch replacement.
Hibernation can't save you if your system suddenly shuts down while you're using it and you have no UPS/battery. The risk of data loss is when there's a power outage and your system is in sleep mode rather than hibernation mode.
It would probably be a good idea test this first on multiple file searches within large directory trees by resetting the index before test.
I'm probably wrong but from what I remember my searches improved somewhat with indexing, at least on 20-60gb directory trees.
You're likely right about Windows Search, but in Win 10 is a lot more than just regular search, it applies to cloud search as well. (I know nobody cares about cloud search btw. I don't either.)
