Poco F3 Alioth to lineageos

[mankokoma]

As the Poco F3 alioth's life ended here, I wanna move on to lineageos. There's recommended to install global OS1.0.2.0.TKHMIXM firmware before flashing lineageos. Is that really necessary or can I just go from here to lineage via TWRP with TKHCNXM from here? Any experiences here?
Thanks.
