At 9 months the EAS routine has ended for most LOs because they eat twice (milk and solids) and their A times and E times have shifted to accommodate changing sleep needs so you are not alone in not having an exact EAS but the idea of not feeding to sleep remains the same as when they are younger - a bit of A between E and S even if it's just a nappy change and wind down routine. There is no need to feed directly after a nap if it is not yet E time.
In the example you give I would just offer the milk earlier, say 10 or 10.15 so that you can get her down for a nap in time. I am assuming you offered breakfast solids around 8.30am as this often helps LOs get through the extra time between milk feeds.
I'd expect her A time to be a bit longer than 3hrs at this age so just be aware of that too, if she is napping really well though there is no need to change her A or S times.
