Hi Panagiotis,
REST is used to avoid the need to go through the GUI.
please, see my feedbacks inlined below...

Could you please provide some more details about "For some reason I was not
able to just update the mosaic"?
(As a note, when doing multiple attempts when creating a new imageMosaic
via REST make sure you don't have partially configured or already existing
layers/stores).
In theory, once you have a workspace defined, you should be able to create
a new ImageMosaic via PUT.
https://docs.geoserver.org/latest/en/user/rest/imagemosaic.html#uploading-a-new-image-mosaic
Afterwards, you may add new granules or update the mosaic, via POST.

In order to configure a GeoTIFF you just need to send the CURL command with
no need to do other things through the GUI.
Provided that you already have a defined workspace (MYWSP), the sample
commands I tested right now are:
curl -v -u admin:geoserver -XPUT --data-binary @sampledata.tif
http://localhost:8080/geoserver/rest/workspaces/MYWSP/coveragestores/MYGEOTIFF/file.geotiff
curl -v -u admin:geoserver -XPUT -d file://D:/data/geotiff/sampledata.tif
http://localhost:8080/geoserver/rest/workspaces/MYWSP/coveragestores/MYGEOTIFF2/external.geotiff
Quoting form the GeoServer doc:
https://docs.geoserver.org/latest/en/user/rest/api/datastores.html#workspaces-ws-datastores-ds-file-url-external-extension
*These endpoints (file, url, and external) allow a file containing either
spatial data [...] to be added (via a PUT request) into an existing data
store, or will create a new data store if it doesn’t already exist. The
three endpoints are used to specify the method that is used to upload the
file:*
*file—Uploads a file from a local source. The body of the request is the
file itself.*
*url—Uploads a file from an remote source. The body of the request is a URL
pointing to the file to upload. This URL must be visible from the server.*
*external—Uses an existing file on the server. The body of the request is
the absolute path to the existing file.*
Whilst the extension parameter
https://docs.geoserver.org/stable/en/user/rest/api/coveragestores.html#extension
*specifies the type of coverage store. The following extensions are
supported:*
*Extension Coverage store*
*geotiff GeoTIFF*
*worldimage Georeferenced image (JPEG, PNG, TIFF)*
*imagemosaic Image mosaic*
Please, let us know.

Daniele
