not possible, it downloads the configuration file <hostname>.cfg if Default
Network Configuration Mode is enabled.

Network Configuration Mode is enabled.
Host-specific Configuration File
The switch attempts to download the host specific configuration file whose name
is specified as the boot file name in the reply from a DHCP/BOOTP server, or is
configured as the Backup Configuration File for DHCP Auto Configuration. The
switch makes three unicast TFTP requests for the specified boot file. If the unicast
attempts fail, or if a TFTP server address was not provided, the switch makes
three broadcast requests to any available TFTP server for the specified boot file.
When the switch gets the configuration file, the configuration is validated for
errors. If the validation is successful, the switch copies the configuration to the
Startup Configuration file type, stores the configuration file name in non-volatile
memory, and reboots the unit.

To resolve the hostname in the configuration file, the switch first downloads
fp-net.cfg from the TFTP server. The fp-net.cfg file is referred as the default
network configuration file and contains one or more IP-address-to-host-name
mappings. The switch determines the hostname from the mappings with its IP
address. If there is no mapping, the switch uses reverse DNS lookup to discover
the hostname.
