Can't Load vfio-pci Module on Ubuntu 18.04 HWE Kernel

```
ubuntu@ubuntu-2:~$ modinfo vfio-pci
modinfo: ERROR: Module vfio-pci not found.

ubuntu@ubuntu-2:~$ uname -a
Linux DL360G9-2 5.4.0-52-generic #57~18.04.1-Ubuntu SMP Thu Oct 15 14:04:49 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
```

But Generic kernel is Working.

```
