We installed Windows 10 on a few different machines and the System Reserved partition varies in size. Sometimes, 50mb, 100mb, and 500mb. Smaller drives sometimes have a larger System Reserved partitions than larger drives. We use the same installation flash drive each time. We've run into problems when the partition was only 50mb and we had to increase the size to be able to update Windows. Is there a way to change this while installing Windows 10?

That's what I've seen everywhere online but that's not what happens. We created the install drive 2 weeks ago from Microsoft's website. Almost every Windows 10 computer I see in general doesn't have a 500mb System Reserved partition.
And actually looking at one of my recently stood up systems (Nov 2020), the Sys Reserved partition is indeed 100MB.

Generally, on Win 10 with a current install USB, it should be 500MB.

Previous Win versions had smaller.

And I am not aware of any method to change this during the install.
