how to root an S8 G950F with security patch of February 1, 2019 and Android 9 - Samsung Galaxy S8 Questions and Answers

hello,
how to root an S8 G950F with android 9 (German official version G950FXXU4DSBA) and security patch of February 1, 2019, whose security activated by mistake when installing TWRP and restart the phone, now if I try to flash with odin the TWRP tells me that you can only flash samsung official software. Is there any way to disable this indicator that my phone is rooted, even if it is not? currently does not open samsung pay, samsung healt and samsung pass. or there is some method of rooting with ADB or other software, which can bypass the security protection.
Thank you for your attention.

How to harden current stock image against the current Bluetooth exploit

I just did a scan with the BlueBorne Vulnerability Scanner on all my devices, my s5 neo is vulnerable for the exploit (my s6 too).
I'm on stock 6.0.1 MMB29K.G903FXXU1BQC1 , security patch level is july 1st 2017 . Is there a way to patch the exploit myself via adb? I need bluetooth for various headsets, so never using bluetooth again is no option.
I do hope to get some kind of official security patch in the next ?? months, but as the s5 and s5 plus were already served with security patches I'm not sure, no love for the s5 neo I guess

Possible to downgrade to stock Android PiE with older security patch?

I have an unlocked Samsung Galaxy S8 (G950F) on stock ROM, Android Pie, on security patch June 2019. Is it possible to downgrade it to stock ROM, Android Pie security patch March 2019 using the Odin method? I have already downloaded the appropriate firmware (G950FXXS4DSC2).
No u can't downgrade anymore , your bootloader is on v5 and there is no way currently to downgrade bootloader to older version
Thank you for your response. Theoretically would I be able to downgrade an S8 on the May 2019 update (G950FXXU4DSE4) to the March 2019 update (G950FXXS4DSC2)? If I am correct the digit after FXXU, i.e 4 represents the bootloader version, which is 4 in this case.

Yes u can downgrade to any earlier pie or Oreo frimware as long u didn't install June update
I thought this was possible too. That's half the reason I rooted. A security update messed up my night mode and it's very annoying. Shame. I doubt Samsung will fix it with any future updates.
