To display sensible data users can enable authentication in my app. I am using 
You can get there from settings here:
What i am looking for is something like this: Here we navigate the user to some other android settings.
Intent intent2 = new Intent();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
intent2.setAction(android.provider.Settings.ACTION_APPLICATION_SETTINGS);
intent2.putExtra(android.provider.Settings.EXTRA_APP_PACKAGE, getPackageName());
} else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP){
intent2.setAction(android.provider.Settings.ACTION_APPLICATION_SETTINGS);
intent2.putExtra("app_package", getPackageName());
intent2.putExtra("app_uid", getApplicationInfo().uid);
} else {
intent2.setAction(android.provider.Settings.ACTION_APPLICATION_SETTINGS);
intent2.addCategory(Intent.CATEGORY_DEFAULT);
intent2.setData(Uri.parse("package:" getPackageName()));
}
startActivity(intent2);

Just figured it out.
There are 3 viable options to use: Settings.ACTION_BIOMETRIC_ENROLL, Settings.ACTION_FINGERPRINT_ENROLL and Settings.ACTION_SECURITY_SETTINGS.
Final implementation I use is:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {
activity.startActivity(new Intent(Settings.ACTION_BIOMETRIC_ENROLL));
}
else {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
activity.startActivity(new Intent(Settings.ACTION_FINGERPRINT_ENROLL));
}
else {
activity.startActivity(new Intent(Settings.ACTION_SECURITY_SETTINGS));
}
}
Settings.ACTION_FINGERPRINT_ENROLL opens this: After chosing backup lock screen method and setup the chosen method, the device will ask you to register a fingerprint.

Settings.ACTION_SECURITY_SETTINGS opens this:

In lack of a device higher than Android Build "R" I could not test ACTION_BIOMETRIC_ENROLL, but I presume it will be similar to ACTION_FINGERPRINT_ENROLL.
If you want to see what options there are to open android settings. You can just use "CTRL" "mouse click" on any Settings.XXX (ACTION_SECURITY_SETTINGS, ACTION_FINGERPRINT_ENROLL, ...) in Android Studio.
You will then see "..\android\platforms\android-31\android.jar!\android\provider\Settings.class"

In case you struggle to figure out which API version is described with "Build.VERSION_CODES.P" you can also click "CTRL" "Mose Click" on the Build version (P, O, ...).
You will then see this:
