Yes, the switchports will form a trunk as switchport mode trunk does not disable DTP.

A switchport configured with switchport mode dynamic auto will also negotiate as a trunk if the connected switchport is configured with switchport mode trunk.

    In addition, if two switches with switchport mode dynamic desirable are connected to each other, the switches will also form a trunk. The list is: Trunk + Trunk = Trunk Trunk + Des = Trunk Trunk + Auto = Trunk Des + Des = Trunk Des + Auto = Trunk Auto + Auto = Access Any + Access = Access nonnegotiate + Trunk = Trunk nonnegotiate + nonnegotiate = Trunk Default is dynamic auto.
