No. Apple's server-side verification requires a valid cryptographic signature. You cannot bypass this signature requirement on modern iOS devices without pre-saved blobs. Why does the error happen on the latest iOS version?
SHSH (Signature HaSH) blobs are a small piece of data that Apple uses to sign iOS firmware. When you restore or update an iPhone, iPad, or iPod, 3uTools requests this signature from Apple to verify that the iOS version you are installing is still authorized. 3utools error unable to request shsh hot

The is a common flashing failure that typically halts the iOS installation process at 9% or 19% , indicating that the software cannot fetch the digital signature required by Apple to verify the firmware . This error occurs because an SHSH blob (Signature Hash Blob) acts as a digital certificate that Apple uses to control which iOS versions can be installed on your device. When Apple stops signing a specific firmware version, or if network restrictions block communication with the verification servers, 3uTools cannot acquire this signature, causing the process to fail. What Causes the "Unable to Request SHSH" Error? A temporary software glitch within the "Easy Flash" mode
If Apple has unsigned the target version, and you have no saved blobs, no tool—including 3uTools—can request SHSH. Apple’s cryptographic walls are unbreakable. You must update to the latest signed iOS version.
