Indeed! Voltage glitching was used to jailbreak Tesla recently! I believe it was also used to jailbreak the Nintendo Switch.
If a discrete TPM (separate chip on the mobo, rather than an fTPM which runs in the CPU/SoC) is in use, one can also use bus sniffing to pwn TPM protection: https://blog.scrt.ch/2021/11/15/tpm-sniffing/
For the Nintendo Switch, it was used to dump some firmware which was then analysed and found to have a buffer exploit (can't remember what sort), which let to the famous Fusee Gelee exploit on early switches. IIRC it was a security chip which is both ironic and incredibly useful because it couldn't be patched without a hardware revision and it ran before anything loaded from the onboard storage.
