You may directly upgrade them all to the latest build.
However, I advise you to upgrade the latest build first (because most likely there won't be any issue). However for older builds , try upgrade them slowly and check if there is any issue and when you are confident everything is fine, then upgrade more clients.
It is also good idea if you use WUfB, take a look at:

HI Everyone.
We are in the process of upgrading all our Windows 10 versions in our environment.

Is it possible to just send a WIndows Upgrade 21h1 to these clients or they can only go for 1909?
Thanks

Aug 6, 2021, 3:08 AM Hi @D1enonly ,
Agree with Reza, we could upgrade windows 10 client to 20H1 directly.
Besides use WUFB, I notice we have the tag of SCCM, is it the environment SCCM? if so, we could use task sequence to upgrade os version.
Here is the article about creating a task sequence to upgrade an OS in Configuration Manager
