Can I stop the System Software Bundle (17.28) from installing and just install Map updates on my Garmin Fenix 7XSS ?

With so many issues with recent Fenix 7 Software Updates (15.77/16.22/17.28 I've had to revert to 14.68 as my OS on my 7XSS, there are a number of Map updates available so can I just install the map updates using GE?

Thanks in advance
