Yes, it is true... ! a few more points to be addressed.
1. The name of the scheme is "bl_kim_gwdo" instead of "bl_ysu_gwdo".
2. Two additional configures in "namelist.atmosphere"
&physics
config_sst_update = false
config_sstdiurn_update = false
config_deepsoiltemp_update = false
config_radtlw_interval = '00:30:00'
config_radtsw_interval = '00:30:00'
config_bucket_update = 'none'
config_kim_tofd = true
config_gwdo_nonhyd = true
config_physics_suite = 'mesoscale_reference'
/
These two red configs are defined as "false" by default.
"config_kim_gwdo=true" should result in an overall decrease of surface
layer wind.
"config_gwdo_nonhyd=true" should result in an overall decrease of GWD
stress by less than 10 % over high mountains. A significant reduction
appears over the Antarctic.

Update of the YSU_GWD scheme (Choi and Hong 2015, JGR), and renamed it as KIM_GWD scheme.
Revisions include sub-grid orographic statistics and configuration of the drag stress and blocking stress, as
described in Hong et al. (2025,WAF)
