How to remap key combo in Solaris VM to avoid a crash

Environment: VMware Workstation Pro running in W10 Pro x64, with a Solaris 10 VM

In the above environment, using the Terminal (using tcsh) program inside Solaris, when I (mistakenly 😅) press Ctrl-Backspace, this causes some fatal error in Solaris, causing the whole VM to crash/reboot. I try to remember not to let my muscle memory take over and perform this key combo but eventually it does and I have to gently bang my head on my desk. How can I remap/disable this key combo so the usual keypress code being generated doesn’t happen?
