What were you trying to do that didn't work?
First installed 4.18.0-372.9.1.el8.x86_64 as base OS
Then using Ansible, upgrade to 4.18.0-372.32.1.rt7.189.el8_6.x86_64:

Then reboot.
1 out of 10 times, the second menu entry (index=1) was used which booted into the old kernel 4.18.0-372.9.1.el8.x86_64
After this incorrect boot, verify the following (using the instruction from https://access.redhat.com/solutions/4326431):

Then reboot again without changing any grub configuration, it chose menu entry index 1 again as default:
If reboot again and choose index 0 manually (4.18.0-372.32.1.rt7.189.el8_6.x86_64), after boot, verify the following:

Then reboot again without changing any grub configuration, the default is index=1 again (4.18.0-372.9.1.el8.x86_64) and boot into the old kernel
==========================================================
compare with a setup in which this issue didn't occur (9 out of 10 times): the printout are identical except the following:
uname -a
Linux 704R7V3 4.18.0-372.32.1.rt7.189.el8_6.x86_64 #1 SMP PREEMPT_RT Fri Oct 7 13:32:56 EDT 2022 x86_64 x86_64 x86_64 GNU/Linux
grubby --default-kernel
/boot/vmlinuz-4.18.0-372.32.1.rt7.189.el8_6.x86_64
In the working setup, uname and grubby default are the same.
They also differ from the below printout:
grub2-editenv /boot/grub2/grubenv list saved_entry=b651008b393b478da50b08dad8ac1d89-4.18.0-372.32.1.rt7.189.el8_6.x86_64 kernelopts=root=/dev/mapper/rhel-root ro console=tty1 rd.lvm.lv=rhel/root rhgb quiet boot_success=1 boot_indeterminate=0 grub2-editenv /boot/efi/EFI/redhat/grubenv list saved_entry=b651008b393b478da50b08dad8ac1d89-4.18.0-372.32.1.rt7.189.el8_6.x86_64 kernelopts=root=/dev/mapper/rhel-root ro console=tty1 rd.lvm.lv=rhel/root rhgb quiet boot_success=1 boot_indeterminate=0
In the working setup `boot_indeterminate=0` exists but not in the setup in which it boot into the old kernel.
