You can work around the lack of the SAGA processing provider by 
installing a plugin.

To install it, you need to enable the 'Show experimental plugins too' 
option in the 'Plugin settings'. After activation you will also find a 
plugin 'Processing SAGA NextGen Provider' in the installation area.

Of course, you also need to install SAGA GIS itself. When you restart 
QGIS after installing SAGA GIS, go to the 'Processing Toolbox' under 
'Providers', 'SAGANG'. There you should enable 'Enable SAGA 
Import/Export optimizations' and add the path to your 'SAGA folder' (= 
executable file).

After these steps the SAGA GIS modules should be displayed in the main 
window of the 'Processing Toolbox -> SAGA Next Gen'.


The plugin 'Processing SAGA NextGen Provider' itself is only delivered 
with interface description files for SAGA GIS v7.2. You can overwrite 
these using the following procedure.

Modern SAGA GIS versions have a tool for generating SAGA interface 
description files via the 'QGIS Tool Interface Generator'. You can 
generate these description files using the following SAGA command:

saga_cmd dev_tools 7 -DIRECTORY='path to the new description files'.

In this directory you will also find a (generated) README with further 
instructions on how to install these files in the QGIS plugin directory 
... ;)

HTH,
