There seems to be no _OSC issue prohibiting (request failed or not granting)
the enablement of ASPM:

$ dmesg | grep -e _OSC -e PCIe -e ASPM
[    0.084223] ACPI FADT declares the system doesn't support PCIe ASPM, so
disable it
[    0.116621] acpi PNP0A08:00: _OSC: OS supports [ExtendedConfig ASPM ClockPM
Segments MSI]
[    0.116775] acpi PNP0A08:00: _OSC: platform does not support [PCIeHotplug
PME]
[    0.116874] acpi PNP0A08:00: _OSC: OS now controls [AER PCIeCapability]
[    0.133733] acpi PNP0A08:00: Disabling ASPM (FADT indicates it is
unsupported)
[    0.554012] r8169 0000:03:00.0: can't disable ASPM; OS doesn't have ASPM
control

$ cat /proc/cmdline
