Buy a laptop that designed for qubes:

Qubes OS has very specific system requirements. To ensure compatibility, we strongly recommend using Qubes-certified hardware. Other hardware may require you to perform significant troubleshooting. You may also find it helpful to consult the Hardware Compatibility List.

Even on supported hardware, you must ensure that IOMMU-based virtualization is activated in the BIOS or UEFI. Without it, Qubes OS won’t be able to enforce isolation.
