Please help me change Panasonic CF-T8 Splash Screen to default

Hi,

Please can somebody help me change or disable a custom Splash screen on a Panasonic Toughbook CF-T8 Laptop? It currently has somebodys custom logo on there and I want it to go back to default or switched off altogether. I have checked the BIOS options and there is nothing obvious currently in there to disable the logo

Model is CF-T8GWE30AE

Many Thanks in advance
