What are other jurisdictions doing about Temp poles as regard to 230.71 requiring a single disconnecting means for services?
Do you know of any manufactures making temp poles that would meet this standard?

We would simply build the pole with a main breaker or disconnect.

Here is NC proposed amendment for those in the state

(B) Two to Six Service Disconnecting Means. Two to six service disconnects shall be permitted for each service by 230.2 or for each set of service-entrance conductors permitted by 230.40, Exception No. 1, 3, 4, or 5. The two to six service disconnecting means shall be permitted to consist of a combination of any of the following:
(1) Separate enclosures with a main service disconnecting means in each enclosure
(2) Panelboards with a main service disconnecting means in each panelboard enclosure
(3) Switchboard(s) where there is only one service disconnect in each separate vertical section where there are barriers separating each vertical section
(4) Service disconnects in switchgear or metering centers where each disconnect is located in a separate compartment
(5) Panelboards for temporary electrical service installations (saw service pole) at a construction site provided all the following:
a. ungrounded circuits do not exceed 150 volts to ground
b. the summation of the ratings of the overcurrent devices that serve together as the disconnecting means does not exceed 100 amperes
c. the number of circuit breaker handles, identified handle ties, or combination thereof that operate as the service disconnecting means does not exceed six operations of the hand

First, 230.71 doesn't strictly require one service disconnect.

Second, why would this be a special problem for temp poles? Most temp poles I've seen are just a meter/main.

I see you are from Iowa. Iowa isn't enforcing that code requirement for used equipment temporary services until January 1, 2022. If you have a new temporary service, as new in new equipment, then April 1, 2021 was the deadline for the requirement.
