With the correct tweak:
options snd-hda-intel model=,dell-headset-multi
added into /etc/modprobe.d/alsa-base.conf

Input source will change form "Analog input" to "Internal Microphone"
And with external headset plugged, two more options "Headset Microphone" and "Microphone" will be available, and the external microphone works with "Headset Microphone" selected
