Need advice: A3 2017 without identification and tracking

Hello,
I want to use my A3 2017 with Oreo firmware and root, but without Google or Samsung account. With all the latest trouble around RMM lock and missing OEM unlock, is this still possible, and what is the best way to get there?
Currently the device is on stock Android 6.0.1 and the OEM unlock option is accessible. Normally my first step would be to update to stock Oreo, then flash TWRP, then Magisk. Now there is a big risk that OEM unlock will be missing after the update. To get OEM unlock back may require logging in with Google/Samsung account and waiting 7 days. Doing that will store Google account info in FRP, which will in turn be protected by RMM lock and so forth. I tried the "software update trick" for OEM unlock on an different device and it did not work, so I don't want to risk losing control of the A3 that I plan to prepare for use.
My goal is to never ever configure any account on the device. When the device is rooted I want to remove or disable all Samsung and Google services. Is that still possible, and how?
Thanks

do not update from ota , download the latest firmware from sammobile flash it then flash twrp then flash magisk from and the frp fix zip (i don't remember the name but search here and you'll find it) before the device boots and then you are good to go

Delete RMM Prenormal after relocking

Hello to all!
Help me remove RMM Prenormal after it was relocked
FRP Off, OEM Off
U2 bootloader, Android 8, firmware SEK-J400FXXU2ARL1
This instruction https://forum.xda-developers.com/galaxy-j/how-to/remove-rmm-prenormal-j4-j6-a6-t3921288 doesb't work
I put the file COMBINATION_FAC_FA80_J400FXXU2ASA1, using iRoot I get root access. But Halabtech 0.9 says Failed when trying to remove RMM
Googled RMM removal through Miracle Thunder https://www.youtube.com/watch?v=vUjD-a_8PeI. I do as per instructions, but RMM remains
Waiting for 170 hours did nothing - OEM Unlock unavailable

Have you tried the Time trick?

Can't install LineageOS on Android 10, should I try on Android 8 first?

I've been trying to install LineageOS 17.1 on my Samsung S9+ without any luck as RMM is stuck in Prenormal, no matter what I try (see here for details). From what Chimera told me and what I've read on gsmhosting, early 2020 Samsung introduced a new lock (Knox?) that leaves RMM in Prenormal no matter what one does. I'm not sure whether this is true, and I'm hoping it is not.
Now, I talked to the reseller I bought the S9 from, and for a fee he's willing to exchange my S9 updated to Android 10 to a new S9 with stock Android 8.
Will I then be able to install TWRP+LineageOS 15 on Android 8? Then if so, will I subsequently be able to upgrade to Lineage 16 (A9), then 17 (A10) without encountering RMM=Prenormal and being stuck again?

FYI, this is the link about RMM being stuck: https://forum.gsmhosting.com/vbb/f777/solution-rmm-prenormal-devices-android-9-10-a-2829610/

Disable FRP Lock permanantly with root?

Hello,
I wanted to root my Samsung Galaxy S9 (SM-G690F), but there is one problem. As soon as I log in with my Google Account and restart the device, I am unable to reboot because of FRP (custom Binary blocked by FRP Lock).
Is there any Magisk Module, Root App or any other Method to permanantly disable FRP Lock?
