Looks like there is no such option in BIOS and I'm unable to find any software to do it from the OS. My laptop model does not appear in https://github.com/torvalds/linux/blob/a7f89616b7376495424f682b6086e0c391a89a1d/drivers/hwmon/dell-smm-hwmon.c#L952

lm-sensors wiki.archlinux.org/index.php/Lm_sensors and s-tui github.com/amanusk/s-tui/blob/master/README.md will show you temp data; looking now for a solution to control fans– K7AAYSep 12, 2019 at 23:39

powersave will control fans on some, not all PCs. thermald may also help. You may need to install the i8kutils package for Dells.
Once installed, you will need to find which sensors correspond with which fans by experimentation and research, then edit configuration files as explained in the above link to enable control and change the set points.
sudo modprobe i8k force=1 might enable dell_smm devices to appear and sensors to show fan[1,2] rpm so you could configure a desirable thermal profile in /etc/i8kmon.conf . You might need to do force=1 since the laptop is missing from https://github.com/torvalds/linux/blob/a7f89616b7376495424f682b6086e0c391a89a1d/drivers/hwmon/dell-smm-hwmon.c#L952
