An update... There is good news and bad news. The good news is that I am now using the kernel driver. Big thanks to the fcomida for the help. The bad news is that I cannot see any wifi networks. Here are the commands and notes for what I have done.

$ install dnf mokutil

I ran "$ mokutil --disable-validation" and set a password.

On reboot, I was given a prompt to run the MOK utility. I had to press a key within 10 seconds to enter the utility I then choose "modify MOK config", entered the password, and chose to disable secure boot. The password required that I enter a single letter of the password (e.g., 4th letter in the password) multiple times.

I was able to successfully run the command

$sudo modprobe -v rtl8723de ant_sel=2

The driver is now used. "$lspci -k" gives

02:00.0 Network controller: Realtek Semiconductor Co., Ltd. Device d723

Subsystem: Hewlett-Packard Company Device 8319

Kernel driver in use: rtl8723de

Kernel modules: rtl8723de

Again, a big thanks to fcomida for the help.

The bad news is that I do not see any wifi networks. "$ ncli radio wifi" returns enabled. But "$ nmcli device wifi rescan" returns.

Error: Scanning not allowed while unavailable or activating.

Likewise, "nmcli device status" returns

wlo1 wifi unavailable --

Help with the next problem is greatly appreciated.
