I don't know if you can stop it from popping up on ios. It doesn't prevent typing though.
FMGo brings that popup whenever a time (or date -) field is active - and it's somewhat annoying since one can quickly change the month instead of a day
I solved this by having text fields for entering date (and time as well), with the numeric iOS keyboard attached. One can enter a date or time manually (what is in this case easier IMHO), a script trigger creates and sends then the correct date (or time) to the real date- or time field. It's just a helper field for entering the data..
Another option is to create a popover with digit keys, a colon and an am pm.
A pop over sounds neat, and as dumb as this will sound, how do you do that ? is it a script ??
Sorry to be such a noob
A popover is a layout object that you can add to a layout. If you are using Filemaker Go, popovers are a must. There are many videos and resources about popovers on the Internet.
This sounds quite similar to the issue with the keyboard appearing when entering a date field on the iPad that was discussed here:
One workaround you could try is to use the script step "Enable Touch Keyboard" to disable (and enable) the keyboard using the OnObjectEnter/Exit script triggers.
