Updating TPM firmware. Need to uninstall 1PW first?

To add clarity to my opening comment, while a check of Settings ( / Updates & Security / Windows Security / Device Security / Security Processor / Security Processor Details & / Security Processor Troubleshooting) and BIOS show that TPM is fully enabled / available, using the steps previously mentioned in earlier posts (RE the use of CERTUTIL in Powershell (won't work in CMD Prompt) and the("Run" / ) MMC snap-in viewer), I can find no direct evidence that any services (keys / tokens / certificates) are actually using the TPM hardware security service currently. If someone has a clearer way of verifying this, I'm all ears. (Hence why it seems just going ahead and installing the TPM firmware update first and then switching over all the software based security items later won't hurt anything, vs if TPM was already being fully utilized, where it would present problems recovering lost access once those hardware-based security items were over-written & lost unless those keys / tokens / certificates were withdrawn and de-activated first).
