Digital signed pdf doesn’t show digital signature in browser, when file open using SPO Doc Lib
I've experienced a similar issues with a different digital signature when viewing via browser.
The only way for me to check an e-signature is to download the file locally and open from the client app since it will need to verify the attached digital certificate. It is understandable that this can be a potential security issue.

Thanks Fred Y jcgonzalezmartin for your time.
I got workaround which work using Data Column Formatting.
Applied below data column formatting to Name Column, Then browser shows the digital signature of PDF file.
