Here I have

%% include.mkiv
\starttext
\externalfigure[img.pdf]
\stoptext

%% do.sh
export SOURCE_DATE_EPOCH=0
export FORCE_SOURCE_DATE=1
context --purgeall
for i in `seq 0 20`; do
 context --nodates   include.mkiv 1>/dev/null;
 cp -v include.pdf include-$i.pdf
done
md5sum include-*pdf


$ bash do.sh
