If there is no spatial autocorrelation, should the spatial cluster detection be performed?

I have a regional count data of disease incidence. First, I calculated empirical Bayes estimate of standardized morbidity rate. Then I performed global Moran’s I to check for spatial autocorrelation of standardized morbidity rate. The result showed that spatial autocorrelation is not significant.

Should I still perform detection of the location of a spatial cluster?
