Hello everyone.
I am here to confirm that this Laptop doesn't have dedicated TPM but the CPU has fTPM (which is called AMD PSP) so it can simple be installed Windows 11. After few days enabling AMD PSP on the bios, the Windows 10 has automatically installed TPM driver on Device Manager. And now it said "Your device is ready to install Windows 11".
Sometimes the seller doesn't understand about the machine they sold.
It can be installed Windows 11.
Thank you all for helping.
