Can I buy the iPhone 14 Pro Max from USA to Bangladesh ?

Be aware the matter of eSIM ~ and other details may affect the usefulness

of an iPhone 14 outside the USA; and might it have no warranty once there.

[From what's been said here in ASC your order may not be processed at all.]

Absolutely. You will need to select your country/region on the Apple website and order online!

Cheers!
