can I reset my iphone passcode from my apple ID account

No.

You need to follow the instructions in this document: If you forgot the passcode for your iPhone, iPad, or iPod touch, or your device is disabled

No you can’t. Sorry.

Passcodes on an iOS device may ONLY be entered and changed locally. (on the device)

If the passcode has been forgotten or misplaced, the ONLY proceedure is to “wipe” (erase) the device w/ a “reset” followed by a “restore” to it’s last backed-up state.
