"Organize my uploads into month- and year-based folder" Option Not Visible in Multisite

For whatever reason, I can’t see the "Organize my uploads into month- and year-based folder" checkbox in Settings > Media.
I’m using WordPress multisite with sub-directories, and it’s a fresh installation. I tried deactivating all plugins, and the theme is "Twenty Twenty-one", but I still can’t see the checkbox.

I guess it’s related to multisite, because the other WordPress (single installation) I have on my host shows the checkbox.

(I’m using WordPress 5.8 + MultiSite)
