What is the Powershell equivalent of "Use the following IP Address" in the IPv4 properties UI?

I am looking for a Powershell command that disables DHCP and sets the machine's private IP as a static IP; basically, I'm looking for the Powershell equivalent of following actions in the UI.

Control panel -> Network and Sharing Center -> Ethernet -> Properties -> IPv4 -> Properties -> toggle off "Obtain an IP address automatically" and toggle on "Use the following IP address" -> fill out IPv4 address, default gateway, and subnet mask.

I want to Powershell this window

The following commands, taken from this guide, seems to describe what I'm after, but Remove-NetIPAddress results in kicking me off the server and locking me out.

$IP = "10.10.10.10"
$MaskBits = 24 # This means subnet mask = 255.255.255.0
$Gateway = "10.10.10.1"
$Dns = "10.10.10.100"
$IPType = "IPv4"
# Retrieve the network adapter that you want to configure
$adapter = Get-NetAdapter | ? {$_.Status -eq "up"}
# Remove any existing IP, gateway from our ipv4 adapter
If (($adapter | Get-NetIPConfiguration).IPv4Address.IPAddress) {
 $adapter | Remove-NetIPAddress -AddressFamily $IPType -Confirm:$false
}
If (($adapter | Get-NetIPConfiguration).Ipv4DefaultGateway) {
 $adapter | Remove-NetRoute -AddressFamily $IPType -Confirm:$false
}
 # Configure the IP address and default gateway
$adapter | New-NetIPAddress `
 -AddressFamily $IPType `
 -IPAddress $IP `
 -PrefixLength $MaskBits `
 -DefaultGateway $Gateway

I'm unable to create a new IPv4 address so long as the existing one is still around, but removing the existing one borks the connection to the server.

That is incorrect. You can set multiple IPs on the same interface. So you simply add the new one with New-NetIPAddress and then remove the previous one.

enter image description here

$currentIP = Get-NetIPAddress | where ipaddress -eq '192.168.43.96'

New-NetIPAddress -InterfaceAlias $currentIP.InterfaceAlias -IPAddress 192.168.43.20 -PrefixLength 24

Remove-NetIPAddress -InterfaceAlias $currentIP.InterfaceAlias -IPAddress $currentIP.IPAddress

enter image description here

The DNS and Gateway are separate things. Just don't change those if you don't need to. To avoid the confirmation prompt, simply add -Confirm:$false to the Remove-NetIPAddress command.
