You can use processors.

\setupalign[righttoleft]

\defineprocessor [lefttoright][style=\lefttoright]
\defineconversionset[lefttorightnumber][][lefttoright->n]

\setupcaption[figure][numberconversionset=lefttorightnumber]

\starttext

\chapter{Chapter}

\dorecurse{20}{\placefigure{Dummy figure}{\blackrule[width=8cm,height=2cm]}}

\stoptext
