Flashing older firmware - Samsung Galaxy S9+ Questions & Answers

Hi everyone, first time posting here so please excuse me if I lack common sense.
I recently flashed lineage OS 17.1 on my s9+ due to there not being a lineage OS for microG rom suitable at the time.
I want to know if its possible to now flash an older lineage OS for microG (15.1) build onto my device as I have a custom bootloader and rom installed.
Otherwise seeing as lineage OS for microG seems to have builds for 17.1 on other devices now, If I were to build my own version using the instructions they give would that mean that 17.1 would work on my s9+?
Cheers!

LineageOS Setup Process On Mate 10 ALP-AL00 w/ TWRP

Hello guys, I am sorry for making a thread like this. I am overwhelmed with the information out there about this process. And I don’t want to brick my device. So, I figured I would ask Here.
I want to install Lineage OS on my Mate 10 (ALP-AL00).
I’m on EMUI 8.1.0 with build number ALP-AL00 8.1.0.350(C00).
My device is rooted, and I have TWRP installed.
What I need is a step by step process on how to install Lineage OS correctly, or, if I am even able to do so with my current setup.
Can I install Lineage OS with TWRP installed, or do I have to remove TWRP first? If so, how?
Thanks in advance to anyone that can help me out!

I'm running on my Mate 10 ALP-L09 LineageOS Beta 5 that I downloaded from openkirin web page. As per information on that web page you must be on EMUI 8.0 (not 8.1) and with stock recovery in order to successfully flash LOS or Omni or RR ROM (BTW. I decided for LOS as in this ROM all of the features and functions that are important to me are working: pictures and videos are saving to SD Card, double tap to sleep works, cast to TV works, hotspot with 5GHz band works, central clock in status bar is available, NFC with magisk's NFC4PRA-GSI module installed works - 5 first features doesn't work for me on Omni Oreo nor Omni Pie) So I think if you want to go for LOS then you first need to back to stock recovery and downgrade to EMUI 8.0. You need to find on XDA how to do that. I can't help you with that because I did LOS installation from EMUI 8.0 with stock recovery.

Update Redmi Note 9 Pro from LOS 18.1 to 19.1 - Need Clarification on Update Process

I'm looking to update my Redmi Note 9 Pro from LOS 18.1 to 19.1, but I'm a bit confused about the update process. Some documentation says that I need to flash Android 12 firmware before installing LOS 19.1. However, others have said that LOS 19.1 is built on top of Android 12 source code, so it includes all necessary updates and features from Android 12.
Can anyone clarify the correct process for me? Here's what I think I'm supposed to do:
Flash LOS 19.1
Flash Gapps
Flash Magisk
Am I supposed to flash the Android 12 firmware before installing LOS 19.1? And should I reboot between any of the things I need to flash? Any help would be greatly appreciated.
