Need to use ssh-rsa for Public Key authentication on Fortiswitches

[epb]

I have a Fortiswitch 148E on FortiOS version 7.4.3 configured to accept public key authentication over SSH. I've found that I need to add "-o PubkeyAcceptedKeyTypes=+ssh-rsa" to my ssh command in order to successfully authenticate via public key as ssh-rsa is disabled by default in OpenSSH in favor of more secure algorithms. This seems like a bit of a security oversight on Fortinet's behalf. Is there any way to enable other public key algorithms in 7.4.3? Any chance this is resolved in 7.6?
