This is your problem. The feature you are trying to use was introduced in GNU Make 4.4, released in 2022. See the NEWS file: https://git.savannah.gnu.org/cgit/make.git/tree/NEWS?h=4.4#n97 Prior to this release, the .NOTPARALLEL special target disabled parallelism for the entire make instance and prerequisites were ignored.
