USB Debugging (with security)
This requires root, shell access with su, and a way to edit text files as root. I used Termux and and android root file manager that can edit text files.
First, run the following command (su first, to switch to root):
setprop persist.security.adbinstall 1

If you also want to enable "USB debugging (Security settings)", for granting permissions, simulating UI input, etc. via ADB, run the following command too:
setprop persist.security.adbinput 1

Next, we need to edit the edit the file
/data/data/com.miui.securitycenter/shared_prefs/remote_provider_preferences.xml

so that MIUI actually lets us do these things:
Add the following line to the XML file (with all the other ones, before the closing tag):
<boolean name="security_adb_install_enable" value="true" />

TWRP
Was in TWRP 3.3.1-9
To install the correct TWRP version, check the "base" of the TWRP indicated after the version number.
E.G. :
twrp-3.6.2_9-0-ginkgo.img is a base Android 9-0
twrp-3.5.2_10-2-ginkgo.img is a base Adndroid 10-2
twrp-3.7.0_12-1-ginkgo.img is a base Adndroid 12-1
Some Android versions cannot decrypt your data folder because of incompatibility issues. Simply downgrade to a lower Android base TWRP.

Enter Fastboot to install latest TWRP

# To check current recovery tool (with phone powered up)
adb reboot recovery

# Boot to recovery
adb reboot bootloader
# Confirm correctly in fastboot
fastboot devices
# Install latest TWRP
cd "/home/wes/Documents/Cellulaires-ROMs/Redmi Note 8"
fastboot flash recovery twrp-3.7.0_12-1-ginkgo.img
# Shutdown phone then "Volume Up + Power" to enter recovery
fastboot reboot

First time installation
You might need to use Lineage OS recovery the first time to initialize a factory reset. Simply follow the instruction here :
https://wiki.lineageos.org/devices/ginkgo/install/variant1#installing-a-custom-recovery-using-fastboot
Sideload the custom ROM rather than Lineage.
