With NTFS you can enable or disable case sensitivity. Is there a way to do it with ext4 in Linux?

    I don't know too much about NTFS, but you can't do that with ext4, there is no known driver for that. Your question seems to be X-Y. Commented Dec 13, 2018 at 4:46

    this would cause random breakages (as seen on macOS which stuck case sensitive unix conventions onto the case insensitive HFS) as some software will have a Makefile but build a temporary makefile, or so forth

There are patches currently under development to implement case insensitivity for ext4.

https://lwn.net/Articles/762826/ https://marc.info/?l=linux-ext4&m=154430575726827&w=2

They were included in the Linux 5.2 kernel, and also require e2fsprogs-1.45 to work. See How to enable new in kernel 5.2 case-insensitivity for ext4 on a given directory?

Nope. Under linux you can do that to fat,vfat,hpfs,ntfs and to iso9660 w/ rockridge extensions. All linux (unix) native file systems I know are case-sensitive.
