can't tell you from my mind fully, but as you already have Azure AD setup with Kerberos working and you have a good guide for Azure AD setup with NTLM, can't you compare the two and work it out?
or even build the NTLM one next to your current one and move over once it works?
the big difference will be that you need to ask for the password as that is needed for NTLM and not for Kerberos. your SSO object will change from Kerberos to NTLM or Basic as shown in the page you. Which means your backend server will also need to allow one of those.
Actually Kerberos one was not working it was setup and when tested it did not work and Backend App was not ready for Kerberos hence whatever configured for Kerberos trying to move to NTLM.
When user tries it shows error as attached. Please advise if you get a hint from it.
One quick note is when user tries they get the Microsoft Landing page , they try to authenticate using email address and I have been told they have to try using email address as user name. However user tested with "DomainName\Username" it did not work too. Azure side they see the log for Authentication as passed but I see error at F5 side as attached.
I will also match as you mentioned above.

a quick search on the error throws up a couple of possible leads, this one seems most useful to check:

Hello ,
After I do medadata import / export manually seems application is accessible with some caveats. I need to fix it.
Problem now user gets too many authentication ask
- Once when user tries to connect for 1st time ( user get microfost online link )
- Then user is presented with F5 Form , interestingly user name field is Non-Editable and not even show the username
- Then from application interface username / password form is presented.
I attached APM Log and APM Policy screenshot if it helps.
I also checked that if user put wrong password at F5 Form it does not allow to move forward.
Question is why user is authenticated 3 times and how I can resolve it ? APM Log says " Could not fine SSO username, check SSO credential mapping agent setting" no idea why it shows this error and does it give any clue ?

sorry i asked for the wrong one i believe, it is probably the first variable assign the one where you use: session.logon.last.usernameUPN.
also can you show the SSO mapping settings?
