In QGIS 3.10, is it possible to only run an algorithm in the processing modeler if certain conditions are true?

I'm applying concave hull to a layer, but sometimes that layer is empty and the model throws an error, so it should only run the concave hull if the layer is not empty.

    Purely no. The functionnality comes with the version 3.14 of QGIS (next month). You can test it now with the nightly version 3.13. However I think it exists some tricks to do that with previous versions. – J. Monticolo May 25 '20 at 11:17

    I think the nightly version is a bit out of my league (or I'm doing something wrong), so if anyone has a workaround I would be very grateful. Otherwise I just have to wait for 3.14.
