Even without hwe, you should be up to 5.4.0-96; have you rebooted since your upgrade? Otherwise you're still using the old kernel.
For further advice, please share output of:
Code:
apt policy linux-generic
If you mean you want newer version than 5.4.x, then you could install hwe or
oem, i.e.:
Code:
sudo apt install linux-oem-20.04d
then reboot.
