Edit your C:\ProgramData\Pulse Secure\ConnectionStore\connstore.dat to include:
machine "settings" { splashscreen-display: "false" }
Use a UNIX line ending capable editor! (Notepad++, PSPad, ...)
PS: Why did you give kudos to somebody who just declined to help you using many words?
is there a similar solution for the macOS client?
I hate splash screens...
