With the rtw88 driver, there have been problems with HP and Lenovo BIOS coding.
Some users have found improvements with use of these two options for rtw88_core
(if using the in-kernel version), or rtw_core (if using the external module
package). Use 'lsmod | grep rtw' to determine which you are using:

parm:           disable_lps_deep:Set Y to disable Deep PS (bool)
parm:           support_bf:Set Y to enable beamformee support (bool)
