We had a similar use-case, albeit it wasn't for a hotfix package.

I think the steps to achieve your goal could be as follows:

(i) you mark your hotfix package as 'tristate' in the *.in file
(ii) you create a collection config that does NOT include the hotfix
package, e.g. using 'ptxdist menuconfig collection
configs/mycollectionconfig'
(iii) run 'ptxdist go' (without any collection config link) to
generate all the packages + hotfix package
(iv) run 'ptxdist --collectionconfig=configs/mycollectionconfig images
=> creates the flash images, but w/o hotfix package applied
