No, however perhaps yes.
As far as I know it is not possible to disable STP on a single port, only on a whole VLAN.
However, say you put your 5 "STP" ports in one VLAN and the "non STP" ports in a second VLAN.
You could then connect the two VLANs with a wire.
This will cost two ports on the switch and I do not know what wll happen to the STP packets. The "non STP" portion will either drop then or flood them.
It may be possible to block such frames with a MAC access-list. This may work on a normal port and will effectively turn off STP,
Why do you need to turn STP off? This is very unusual.

Typically yes ... "spanning-tree bpdufilter enable" will stop the port sending and receiveing bpdu's.
