I tried with the files

The "blacklist" entries prevent a module being loaded by its alias
(typically a PCI ID), but not from being loaded if something explicitly
loads it by module name. Most likely, those modules are included in
your initrd.
I'd suggest using the entries described above, and editing grub.conf to
add arguments to the kernel command line:
rd.driver.blacklist=mlx5_core rd.driver.blacklist=mlx5_ib
... then rebuilding your initrd using "dracut --force"
Thanks for the hint. However as this should only be a temporary measure
and needs to be done on ca. 100 hosts I'm not sure if we want to go
through the hassles. Deploying a textfile is no problem, but creating
new initrds for differing hardware....
