I don't have an AMD motherboard but I agree 1.50v is way too high, especially at stock settings.
LLC is a good setting to start with, I use LLC to help keep the voltage (Vcore) close to the voltage I set in the bios. A lower value should help get the maximum Vcore to a lower voltage.

Stock values are usually set pretty high to cope with underwhelming cpu's.
Try manually setting a lower cpu voltage and playing with LLC, you may have to try adaptive or offset mode.
This is about all I'm going to have as I am not familiar with your bios.

1.5v is normal for this platform and is intrinsically related to how Zen handles idle voltage and parks cores. Many Intel users fall trap to these levels when crossing over to team red.
What's important is the sustained voltage when the CPU is under high current loads. Around 1.325v is a good ceiling to keep for these types of workloads.

After speaking with The Stilt, whose name is featured in most ROG motherboard BIOSes, he disagrees that 1.5500V is acceptable VID. He's manually confirmed that my CPU is factory set to 1.50000V and the Asus B550-E is doing something to force that to 1.5500V, which in turn causes higher Core SVI2 TFN readings. I imagine he's registered here and can confirm the public and private conversation I've had with him.
The Stilt spent an entire day looking through 9 BIOS version over two Asus motherboards and couldn't work out what you've done to violate AMD's factory limit. Can you, or someone from Asus, please explain? I don't mind showing proof of this conversation with The Stilt privately with an Asus employee and providing more information.
tldr; At entirely stock settings in the BIOS, Asus is doing something to force vmax over 1.50000V to 1.55000V. This does not meet AMD's stock specifications. BIOS version is 2423 "AMD AM4 AGESA V2 PI 18.104.22.168 Patch C".

How are you measuring the core voltage? Are you solely basing all this on the SVI2 TFN readout?
Can you forward me any information you have, please.

It's more VID, which The Stilt pointed out is going against AMD's specification and the CPU's factory-set vmax. I'll send you a private message with how The Stilt confirmed the voltage and with a couple of threads explaining his testing.
