You can certainly ask Apple, but you'll be very unlikely to get your wish. Read this about Spatial Audio:
The new spatial audio feature works by using directional audio filters and tracking, which adjusts sound frequencies in each ear as you move. This is achievable thanks to a gyroscope and accelerometer in your AirPods Pro and your iPhone, which work together to track your head and device's movements. By comparing the motion data, spatial audio changes the field of sound to stay in exactly the right place, even as you're moving your head or device. Basically, it's a movie-theater experience in your ears.
Reading this leads me to believe the iPad Pro you own must lack the hardware required for the feature to work. iPhone 6s, and iPhone SE first generation, also get iOS 14, but cannot use Spatial Audio.
The following devices are capable of using Spatial Audio:
iPhone 7 or later
iPad Pro 12.9‑inch (3rd generation) and later
iPad Pro 11‑inch
iPad Air (3rd generation)
iPad (6th generation) and later
iPad mini (5th generation)
