<pre> I am using QGIS 3.20.0-Odense and I have a small set of points in
EPSG 4326, a geographic projection. I am trying to use the Multi Ring
Buffer tool and the units for the buffer distance is in "degrees" but I
want to specify a buffer of 5 metres.</pre>

Hi Bernie,<br>
if you are using the "Multi-ring buffer (constant distance)" QGIS
processing algorithm, then AFAIK the unit for the "distance"
parameter depends on the unit of the CRS of the input layer and not
of the CRS set for the project.<br>
<br>
So, in order to specify the distance in metres, you need to
reproject the layer in a projected coordinate system whose unit is
metres and use such projected layer as the input of the algorithm.
Pay attention to to reproject your layer to a projected CRS (usually
an UTM one) that is adequate for your study area in order to
minimize the projection distortion.<br>
<br>
