How to change pcie_aspm settings on ubuntu server?

Running a server with a pci-express solid state drive, after some i/o read errors i have the suspicion that my drive is shut down thanks to the pcie_aspm manager. (why one would save power on a server -_-)
While trying to edit the pcie_aspm in the /etc/default/grub file, I found that it is not actually configuring it and the pcie_aspm remains in the default mode, checking the state of pcie_aspm in /sys/module/pcie_aspm/parameters/policy. This is set to default, no matter what I try.
Clear steps:
- changing
/etc/default/grub:GRUB_CMDLINE_LINUX_DEFAULT=""=>
GRUB_CMDLINE_LINUX_DEFAULT="pcie_aspm=performance"
- running
update-grub
- rebooting and checking
/sys/module/pcie_aspm/parameters/policy
- no change :(
help would be appreciated since the server is a bit unstable because of this!
Update:
To clarify a little bit more:
OS: Ubuntu Server Ubuntu 16.04.5 LTS
Several sources claiming different solutions (I know these are not the same distro's but at some point you try different things):
Source 1 => pcie_aspm.policy=performance in /etc/default/grub
Source 2 => pcie_aspm=performance in /etc/default/grub
Source 3 => # echo powersave > /sys/module/pcie_aspm/parameters/policy
These did not work for me.
